Question

I have this loop in PHP that echoes out a table of results,

<table cellspacing="0" cellpadding="3">
  <tr>
    <td><b>Content Image Title</b></td>
    <td><b>Content Image Type</b></td>
    <td><b>Headline Image</b></td>
    <td><b>Content Image Belongs To</b></td>
    <td><b>Date Created</b></td>
    <!--<td><b>Uploaded By</b></td>-->

  </tr>
  <?php $colours = array("#f9f9f9", "#f3f3f3"); $count = 0;?>
  <?php foreach ($allContentImages as $contentImages) : ?>
    <tr bgcolor="<?php echo $colours[$count++ % count($colours)];?>">
      <td><?php echo "<a href='#' class='screenshot' rel='/media/uploads/$contentImages[categoryId]/$contentImages[contentImageName]'>".$contentImages['contentImageName']; ?></td>
      <td><?php echo $contentImages['contentImageType']; ?></td>
      <td><?php if($contentImages['isHeadlineImage'] == 1){ echo "Y";}else{echo "N";} ?></td>
      <td><?php echo $contentImages['contentTitle'] ?></td>
      <td><?php echo date("d-m-Y", $contentImages['contentImageDateUploaded']); ?></td>
      <td align="left"><a class="delete" href="<?php echo base_url();?>dashboard/deleteContentImage/<?php echo $contentImages['contentImageId'];?>"><img src="/media/images/icons/cancel.png" alt="Delete A Category"/></a></td>
    </tr>
  <?php
    if($contentImages['isHeadlineImage'] == '0') {
        echo "<tr bgcolor='red'>";
        echo "<td><p>You need to assign a headline image</p></td>";
        echo "</tr>";

  ?>
  <?php endforeach; ?>
</table>

I need to check for each content piece with the same title that there is headline image, and if not then echo a new row that is red…but all I get is a new row every time there is an image that is not a headline image. Can anyone help me? I don’t mind using javascript if that helps to match the values of the td’s? But obviously my attempt is not correct.

It sounds like what you want to do has to be precalculated, since the foreach loop can not know about future content.

Maybe something like this before your foreach statement:

$contentHasHeadlineImage = array();
foreach ($allContentImages as $contentImages) {
  if ( $contentImages['isHeadlineImage'] == 1)
    $contentHasHeadlineImage[ $contentImages['contentTitle'] ] = true;
}

And then you can use

if (array_key_exists($contentImages['contentTitle'], $contentHasHeadlineImage)) {
  // Has headline image... 
}

to to verify if a certain title has a headline.
