Hoi allemaal,

Ik heb hier een textarea, die voorzien moet worden van tekst uit een php string:
HTML: 
          <textarea id="elm1" name="thearticle" cols="15" rows="40"><?php echo $thearticle; ?></textarea>

Waarom blijft de textarea leeg?

mr32 :cool:
 
Waarschijnlijk omdat je php variabele leeg is.

Heb je al gecontroleerd of er wel wat in zit?
 
Ja, ik heb bovenaan de pagina het getest d.m.v.
PHP: 
echo $thearticle.'<br />';

En hij gaf keurig de juiste waarde door...
 
Hm, en als je in de source code van de HTML pagina kijkt? (control + U op de pagina waarschinlijk)

Staat dan de tekst wel in de source? Of staat er niks tussen de textarea tags? Het zou kunnen dat de value op dat punt niet bestaat, misschien.
 
HTML:

In de codes heb ik nog wat comments toegevoegd...
 
maar in die code zie ik bij <textarea>""</textarea> staan ipv <><?php echo $variable; ?></> en waar haal jij die variable weg? ik zie nergens waar je die $thearticle weghaalt
 
Die vorige code was de broncode weergeven door de browser, hier zal ik de originele code's plaatsen:

PHP: 
<?php
 $allowedTags='<p><strong><em><u><h1><h2><h3><h4><h5><h6><img>';
 $allowedTags.='<li><ol><ul><span><div><br><ins><del>';  
// Should use some proper HTML filtering here.
  if($_POST['elm1']!='') {
    $sHeader = '<h1>Ah, content is king.</h1>';
    $sContent = strip_tags(stripslashes($_POST['elm1']),$allowedTags);
} else {
    $sHeader = '<h1>Nothing submitted yet</h1>';
    $sContent = '<p>Start typing...</p>';
    $sContent.= '<p><img width="107" height="108" border="0" src="/mediawiki/images/badge.png"';
    $sContent.= 'alt="TinyMCE button"/>This rover has crossed over</p>';
  }
  
	require_once('../includes/DbConnector.php');
	require_once('../includes/Validator.php');

	$connector = new DbConnector();
	

	
  // Verkrijgen van artikel id, en daarbij laadt hij de juiste waarden
  if($HTTP_GET_VARS['action'] == 'bewerk') {
	
	$artikelID = $HTTP_GET_VARS['id'];
	$result = $connector->query('SELECT ID,title,tagline,thearticle,section FROM cmsarticles WHERE ID = '.$HTTP_GET_VARS['id']);
	

	$row = $connector->fetchArray($result);
	
	
	$title = $row['title'];
	$tagline = $row['tagline'];
	$thearticle = $row['thearticle'];
	
	echo $title.'<br />';
	echo $tagline.'<br />';
	echo $thearticle.'<br />';
}

Op regel 97 staat
PHP: 
<textarea id="elm1" name="thearticle" cols="15" rows="80">"<?php $thearticle;?>"</textarea>
zonder "echo" voor "$thearticle".
