PHP - Node Order

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 am new to xml parsing and I just want to know how to check whether a node has attributes:

Here is my xml file to use:
=================
Code: [Select]
<?xml version="1.0" encoding="ISO-8859-1"?>
<email>
<message>
<to>
<toFirstName>Tove</toFirstName>
<toLastName toType="common" style="swag">Smith</toLastName>
</to>
<from>
<fromFirstName>Jani</fromFirstName>
<fromLastName fromType="unique">Dravison</fromLastName>
</from>
<heading>Reminder</heading>
<body>
<prologue>Tis the night before Xmas...</prologue>
<paragraph1>Don't forget me this weekend!</paragraph1>
<paragraph2>Jump the gun!</paragraph2>
<epilogue>The end of the world.</epilogue>
</body>
</message>

<message>

<prologue></prologue>
<paragraph1>Year over year data</paragraph1>
<paragraph2>Downsizing</paragraph2>
<epilogue>The end.</epilogue>
</body>
</message>
</email>

Here the simple script that I cannot get to work:
==================================
Code: [Select]
<?php
$simpleXMLObj=simplexml_load_file("email.xml");

if($simpleXMLObj->to[0]->toLastName[0]->attributes()->getName)
print "YES: this node has attributes!";
else
        print "NO:";
?>

Please I really need help, it is simple I know but I am new to xml parsing and mixed up.

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

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

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!

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.

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>

I've got.

I got this code from a previous thread:

Code: [Select]
mysql_query("SET @rows = 0;");
$res = mysql_query("SELECT @rows:=@rows+1 AS view_rank,COUNT(id) AS views, credit_members_id FROM vtp_tracking GROUP BY credit_members_id ORDER BY views DESC");
$n   = array(1 => 'st', 2 => 'nd', 3 => 'rd');
while($row = mysql_fetch_row($res))
{
   if ( $row[2] != $members_id )
      continue;
   if ( substr($row[0], -1) < 4 )
   {
      $row[0] .= $n[$row[0]];
   }
   else
   {
      $row[0] .= 'th';
   }
   echo ' You are in ' . $row[0] . ' place with ' . number_format($row[1]) . ' views.';
   break;
}
Everything seems ok except it orders by the "credit_members_id" and not "views" as entered.

Can someone explain why, and how to fix this?

Currently i have a query which at the end has this
Code: [Select]
order by (value/counter) desc");

which works fine, however i was wondering, if in the case that 2 rows have the same, is it possible to set a second value to order by?

I need to make 0, which displays as POA appear at the ned of the list not at the begining, I currently just use
order by price asc

and 0 is at the beginning, i need to make 0 at the end

Hi there, just registered and in need of help, this looks a good place to start!
I'm a php beginner so please bear with me

I have a mysql database which holds 3 pieces of info
id:
match:
1:

I'm trying to sort the results using ORDER BY match ASC but for some reason it's just not for having it...
Can't work out if it's an error with my php code or my table. I can order by "ID" no problem but I when I try ordering alphabetically by "match" it won't.

my code is:

Code: [Select]
mysql_connect("***.***.***") or die(mysql_error());
mysql_select_db("database") or die(mysql_error());


$query = "SELECT * FROM employees WHERE flag = 'tv' ORDER BY match ASC";
$result = mysql_query($query) or die ("Query failed");

$numrows = (mysql_num_rows ($result));


       

// loop to create rows
if($numrows >0){
echo "<table width = 100% border = '0' cellspacing = '2' cellpadding = '0' >";
// loop to create columns
$position = 1;
while ($row = mysql_fetch_array($result)){
if($position == 1){echo "<tr>";}
 
echo " <td align = 'center'><a href=\"http://www.website.eu/sport-stream/1/{$row['id']}.html\" target=_blank>{$row['match']}
<br>
<img src=\"{$row['8']}\" width=\"100\" height=\"70\" /> </a>
</td>

";
if($position == 4){echo "</tr> "; $position = 1;}else{ $position++;}
}//while

$end = "";
if($position != 1){
for($z=(4-$position); $z>0 ; $z--){
$end .= "<td></td>";
}
$end .= "</tr>";
}

echo $end."</table> ";
}//if
And here's a cap of my database:


any help for a php n00b would be greatly appreciated!
