[SOLVED] getfirst() error

[mr_badger]

I'am getting an error Fatal error: Call to undefined function: getfirst() in \sitename on page 123. everything works fine on localhost.

<?php do { ?>
      <h2><?php echo $row_getArticle['title']; ?></h2>
      <p><strong><span class="style1"><?php echo $row_getArticle['theDate']; ?></span></strong><span class="style1"><strong>:</strong></span>
  <?php $extract = getFirst($row_getArticle['article'], 2);
  echo $extract[0];
  if ($extract[1]) { ?> <a href="blog_detail.php?article_id=<?php echo $row_getArticle['article_id']; ?>">More</a> <?php } ?></p>
      <?php } while ($row_getArticle = mysql_fetch_assoc($getArticle)); ?>
  
      <table width="50%" border="0" align="center" id="first_prev">
        <tr>
          <td width="23%" align="center"><?php if ($pageNum_getArticle > 0) { // Show if not first page ?>
                <a href="<?php printf("%s?pageNum_getArticle=%d%s", $currentPage, 0, $queryString_getArticle); ?>">First</a>
                <?php } // Show if not first page ?>
          </td>
          <td width="31%" align="center"><?php if ($pageNum_getArticle > 0) { // Show if not first page ?>
                <a href="<?php printf("%s?pageNum_getArticle=%d%s", $currentPage, max(0, $pageNum_getArticle - 1), $queryString_getArticle); ?>">Previous</a>
                <?php } // Show if not first page ?>
          </td>
          <td width="23%" align="center"><?php if ($pageNum_getArticle < $totalPages_getArticle) { // Show if not last page ?>
                <a href="<?php printf("%s?pageNum_getArticle=%d%s", $currentPage, min($totalPages_getArticle, $pageNum_getArticle + 1), $queryString_getArticle); ?>">Next</a>
                <?php } // Show if not last page ?>
          </td>
          <td width="23%" align="center"><?php if ($pageNum_getArticle < $totalPages_getArticle) { // Show if not last page ?>
                <a href="<?php printf("%s?pageNum_getArticle=%d%s", $currentPage, $totalPages_getArticle, $queryString_getArticle); ?>">Last</a>
                <?php } // Show if not last page ?>
          </td>
        </tr>
  </table>

 

I manage to get the title and date fine but nothing else. The error is this line

<?php $extract = getFirst($row_getArticle['article'], 2);

Where do you define getFirst() ?

[mr_badger]

what do you mean by where have I defined it? Sorry if this is a stupid question.

getFirst() is not a php function. You must have defined it somewhere. Now php can't find it (and neither can you by the sounds of it... hehe). It will look something like...

 

<?php

  function getFirst($a,$b) {
    // relevant code
  }

?>

like thorpe said, you have to write the getfirst() function yourself.

Yes you are right, I had the getfirst function definition in another file and forgot to add it to the original code, thanks for the help.
