PHP - Update Xml Node
How do I update an xml node?
Currently I have this: $xml = simplexml_load_file($xmlfile); $user = $xml->xpath('/root/users/user/name'); $usr = $user[0][0]->asXML(); $usr = $name; I don't know if that I right or not, but I do know that if it is right, it isn't updating the xml file. Am I on the right track, or not? What can I do? Similar TutorialsHello I have xml like this. <?xml version="1.0" encoding="utf-8"?> <data> <item ID="30001"> <Company>Navarro Corp.</Company> </item> <item ID="30002"> <Company>Performant Systems</Company> </item> <item ID="30003"> <Company>Digital Showcase</Company> </item> </data> All i need to do is get any one of the whole node from starting item tag to ending item tag from the xml, for example. getting <item ID="30002"> <Company>Performant Systems</Company> </item> from whole xml file. Can this be achieved using SimpleXML object from PHP? if not how it can be done. Thanks in advance watsmyname I'm trying to delete the <identifier> node of some XML, using the following code; unsuccessfully.
Can someone help me identify where I'm going wrong? TIA
$newXML = ""; $xmlString = Fedora_API::callGetDatastreamContents($this->pid, 'MODS', true); $doc = DOMDocument::loadXML($xmlString); $xpath = new DOMXPath($doc); $fieldNodeList = $xpath->query("/identifier"); foreach ($fieldNodeList as $node) { $fieldNodeList->removeChild($node); } $newXML = $doc->SaveXML(); Can someone please explain to me what's the importance of node order? Does certain nodes that appear first or last have impact on traversing time? Any suggestions much appreciated! I'm trying to add/update an xml like so: $xml->Header->Record->$curblk->$row = $value; where $curblk and $row are obviously nodes. Problem is that sometimes I need to add/update nodes of the same name so I tried this: $xml->Header->Record->$curblk->$row[$multi] = $value; where $multi would represent the number (or instance or key?) of that node I wish to add/update. Issue with that is, php thinks that I'm tring to set the node as an array, which is not possible! So how do I dynamically add/update $row[0] , $row[1] , $row[2] base on the two variable, $row and $multi? ie: $row = Jim Bob; $multi = 0; <author>Jim Bob</author> $row = Tom Reed; $multi = 1; <author>Tom Reed</author> You get: <book> <author>Jim Bob</author> <author>Tom Reed</author> </book>Of course there is muuuuch more to it than that, but that is about as simple as I can explain it... Of course thank you for any help, i've been stuck on this for 3 days now! and my boss is not happy, especially since I'm a vary novice developer that took on this assignment... XML file:
<?xml version="1.0" ... > <database xmlns:xsi="http://www.w3.org/20...hema-instance"> <record> <id>1</id> <name></name> </record> <record> ... </record> </database> I want to delete the record where <id> equals $_GET['id']. I tried many suggested implementations based on xml or simplexml, without result. Came across a very simple workaround (it should omit the record where id=$id), but can someone help me to taylor it to my xml scheme? <?php $file = "database.xml"; $id = $_GET['id']; echo "DELETING: ".$id; $xml = simplexml_load_file($file); $str = "<?xml version=\"1.0\"?> <database>"; foreach($xml->children() as $child){ if($child->getName() == "id") { if($id == $child['name']) { continue; } else { $str = $str.$child->asXML(); } } } $str = $str." </database>"; echo $str; $xml->asXML("database_backup.xml"); $fh = fopen($file, 'w') or die("can't open file"); fwrite($fh, $str); fclose($fh); ?> Hi All, I've been struggling to get the following code to work. I have an API feed that looks like this:
<Jobs> <Job> <ID>1805</ID> <Name>House Additions/Alterations </Name> <Description>House</Description> <Client> <ID>16178470</ID> <Name>client name 1</Name> </Client> <ClientOrderNumber></ClientOrderNumber> <State>In Construction</State> <StartDate>2018-03-26T00:00:00</StartDate> <DueDate>2020-03-31T00:00:00</DueDate> <Contact> <ID>10195532</ID> <Name>Clent Name1</Name> </Contact> <InternalID>25026686</InternalID> <Manager> <ID>610781</ID> <Name>Manager Name 1</Name> </Manager> <Partner> <ID>610781</ID> <Name>patner name</Name> </Partner> <Assigned> <Staff> <ID>610781</ID> <Name>Staff 1</Name> </Staff> ......... I'm trying to work out how to show all the job ID, Job Name, Client Name, Start Date etc that are specific to the assigned staff member by selecting a specific staff member. $Staff is populated by a dropdown earlier in the code. here's my code so far: if ($err) { echo "cURL Error #:" . $err; } else { $xml=simplexml_load_string($response) or die("Error: Cannot create object"); $jobs = $xml->xpath("Jobs/Job/Assigned/Staff[Name= '$Staff']"); foreach($jobs as $item) { //foreach($xml->Jobs->Job as $item) { $item1 = $item->Client->Name; $job_no = "$item->ID"; $job_name = "$item->Name"; $job_client = "$item1"; $job_start = "$item->StartDate"; $job_due = "$item->DueDate"; $job_status = "$item->State"; echo "<tr><td>$job_no</td><td><a href='activecp/managejob.php?job_id=$job_no'>$job_name</a></td><td>$job_client</td><td>$job_status</td><td>$job_start</td><td>$job_due</td></tr>"; } } This currently shows the ID and name of the selected staff member but not the info i need. All of the data I want to show is before the Assigned/Staff . Any help would be much appreciated. Thanks in advance. I would like to adding a node to a tree. I want it to be a balanced b-tree. The logic/algorithm i can think of is Code: [Select] <?php function add_node($root, $node) // Where $root is the parent to which node should be added and $node is the node that is to be added. { Traverse the tree level wise, level 1 being the lchild and rchild of $root and calculate the number of node in that level if(number of nodes in a level < 2[sup]$level[/sup]) // Since number of nodes a level can accommodate = 2[sup]$level[/sup] { Add node in that level where ever it gets an empty spot. } } ?> Tree table:- Code: [Select] CREATE TABLE IF NOT EXISTS `tree` ( `parent` int(7) NOT NULL, `rchild` int(7) NOT NULL, `lchild` int(7) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; Is their any better logic to do so ? Hi, I have a RSS feed cached as an XML file. I need to pull some info out of it so I can then print it to the page. Currently I am using this code to extract the data: $doc = new DOMDocument(); $doc->load('inthenews.xml'); $inthenews = array(); foreach ($doc->getElementsByTagName('item') as $node) { $itemRSS = array ( 'title' => $node->getElementsByTagName('title')->item(0)->nodeValue, 'link' => $node->getElementsByTagName('link')->item(0)->nodeValue, 'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue, ); array_push($inthenews, $itemRSS); } However, the Description node contains more than I want. I need to remove everything except for the image ( <img../> ) it contains. Is there some way of running preg or similar on the nodeValue as it is extracted? Or an alternative to "getElementsByTagName" that allows searching for strings? If not, does anyone have a suggestion for doing this? I tried running preg_replace on the array, but it doesn't seem to do anything?? An example of the Array created by my code above is shown below: Code: [Select] [0] => Array ( [title] => BBC radio Cambridge 7.20am [link] => images/news/Matthew_Freeman_Radio_Cambridgeshire_21-10-10.mp3 [desc] => <img alt="BBC-logo" src="http://www2.mrc-lmb.cam.ac.uk/images/news/BBC-logo.jpg" height="54" width="127" /><br/>BBC radio Cambridge 7.20am 21.10.10: Dr Matthew Freeman"<br/> 21 October 2010 ) Thanks in advance for any advice Phil I am creating a football predictor game and have a table in the database to hod all my users i have written a query to pull all out the users that have made a prediction that day with their predictions made i have put this into an array so my array will hold all the user details 1 being their userId I have set the order by on the query to userId so I get all the same users predictions in 1 block. I now want to extract all the predictions for each user and put these into their own array but I don't know which users the array will hold, how many users their will be, or how many predictions each user would have made so i'm not sure how to create this array i'm quite new to php can anyone help me with this How can I print the attributes of a child node?

Hey guys. I just recently started learning php and I like to learn hands on. So, my first project involves the Google Calendar. I found a script on github that is basically a Google calendar feed and I've been manipulating it to meet my personal needs and expectations, but the only thing I am struggling with is the xml part. All I want to do in this case is get the value from ###TITLE### (after it is sorted by newest date which is done automatically in the script) and store it in a new variable but no matter what I try or do and after reading a bunch of material on xml and php, I still cannot get it to work. If anyone knows how to do this and provide an explanation so I can actually learn I would really really appreciate it. Here is the github script https://github.com/m...ter/gcalphp.php
Thank you and I am looking forward to any suggestions or anything.
Hi, I need to build my own xml validator and was wondering, what are some possible purposes of having multiple text nodes for a given parent node, I ask b/c while I was playing around with W3schools XML validator, I noticed it successfully validated the following: <?xml version="1.0" encoding="utf-8" ?> <note> <to>Joh</to> <from>Frank</from> <body>Hello world</body> Extra text node that is validated! </note> I am trying to use php to loop through an xml file and reorganize the data. For example, if I have a xml file about books and the first xml sub tag under the <book> tag is "<type>" . I would like to make the following tags (nodes?) as child nodes under the type tag. For example, instead of this: Code: [Select] <book> <type>nonFiction</type> <title>Advanced PHP Programming</title> <author>George Schlossnagle</author> <publisher>Developer Library</publisher> <category>1</category> <category>3</category> </book> <book> <type>Fiction</type> <title>My Novel</title> <author>Same Nagle</author> <publisher>Developer Library</publisher> <category>1</category> <category>3</category> </book> I want to make the xml look like this: Code: [Select] <book> <type>nonFiction <title>Advanced PHP Programming</title> <author>George Schlossnagle</author> <publisher>Developer Library</publisher> <category>1</category> <category>3</category> </type> </book> <book> <type>Fiction <title>My Novel</title> <author>Same Nagle</author> <publisher>Developer Library</publisher> <category>1</category> <category>3</category> </type> </book> [attachment deleted by admin] Can anyone post a generic update function to update mysql table.

Notice: Undefined variable: stmt in C:\xampp\htdocs\Cust_App\update.php on line 47 and errors with the Update statement
Notice: Undefined variable: stmtupdate in C:\xampp\htdocs\Cust_App\update.php on line 96 I had defined the customerID variable above in the code, but it isn't being captured from here. I tried setting up this query like the one which gathered the data, but I'm off by a little bit. I would like the option to be able to update all fields. Any help is appreciated. I'm trying to learn as I may get asked to update other forms in the future. (new boss asks a lot) <?php require_once('database.php'); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <!-- the head section --> <head> <title>My Guitar Shop</title> <link rel="stylesheet" type="text/css" href="main.css" /> </head> <!-- the body section --> <body> <div id="page"> <div id="header"> <h1>SportsPro Technical Support</h1> <p>Sports management software for the sports enthusiast.</p></h1> </div> <div id="main"> <h1>View/Update Customer</h1> <form action="update.php" method="get" > <?php if(isset($_GET['customerID'])) { $customerID = filter_input(INPUT_GET, 'customerID', FILTER_SANITIZE_NUMBER_INT); $sql = "SELECT * FROM customers WHERE customerID =$customerID "; $stmt = $db->query($sql); } ?> <div id="content"> <!-- display a table of products --> <h2>Customers</h2> <form method = "edit"> <?php foreach ($stmt as $cust) { ?> <div> <label>First Name</label> <input type="text" name="name" class ="form-control" value ="<?php echo $cust['firstName']; ?>"> </div><br> <div> <label>Last Name</label> <input type="text" name="name" class ="form-control" value ="<?php echo $cust['lastName']; ?>"> </div><br> <div> <label>Address</label> <input type="text" name="address" class ="form-control" value ="<?php echo $cust['address']; ?>"> </div><br> <div> <label>City</label> <input type="text" name="city" class ="form-control" value ="<?php echo $cust['city']; ?>"> </div><br> <div> <label>State</label> <input type="text" name="state" class ="form-control" value ="<?php echo $cust['state']; ?>"> </div><br> <div> <label>Country</label> <input type="text" name="countryCode" class ="form-control" value ="<?php echo $cust['countryCode']; ?>"> </div><br> <div> <label>Zip Code</label> <input type="text" name="postalCode" class ="form-control" value ="<?php echo $cust['postalCode']; ?>"> </div><br> <div> <label>Email </label> <input type="text" name="email" class ="form-control" value ="<?php echo $cust['email']; ?>"> </div><br> <div> <label>Phone Number </label> <input type="text" name="phone" class ="form-control" value ="<?php echo $cust['phone']; ?>"> </div><br> <div> <label>Password </label> <input type="text" name="password" class ="form-control" value ="<?php echo $cust['password']; ?>"> </div><br> <div> <?php } ?> <input type="Submit" name="Update_Data" value="Update Data"></input> <?php $sql2 = "UPDATE customers SET firstName = ". $stmtupdate['firstName']."

I created this code to upload a member's main picture on his member page on website. I'll only include the query part of the code since that's what is relevant to my problem. The idea is basically to upload a new picture onto the database if no picture already exists for that member and display the picture on the page. If a picture already exists, then the script replaces the old picture with the new one upon upload. But for whatever reason I don't understand, when I try to replace the old pic, it gets inserted in a new row on the database instead of replacing the old row, and the new pic gets displayed on the web page alongside the old. Code: [Select] $query = "SELECT username FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main'"; $result = @mysql_query($query); $num = @mysql_num_rows($result); if ($num> 0) { //Update the image $update = mysql_query("UPDATE images SET image = '" . $image['name'] . "' WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main'"); $_SESSION['error'] = "File updated successfully."; //really should be session success message. header("Location: member.php"); exit; } else { // NOTE: This is where a lot of people make mistakes. // We are *not* putting the image into the database; we are putting a reference to the file's location on the server $sql = "insert into images (member_id, image_cartegory, image_date, image) values ('{$_SESSION['id']}', 'main', NOW(), '" . $image['name'] . "')"; $result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error()); $_SESSION['error'] = "File uploaded succussfully."; //really should be session success message. header("Location: member.php"); } So can anyone tell me what the problem is? Could the fact that my insert script actually uploads the image onto a folder on my server and only stores the path name in the database have anything to contribute to the mixup? Appreciate your responses in advance. |
