将PHP foreach中的变量添加到引导模式

Question

I have a button within a php foreach statement which loads a modal. How can i pass the particular id ($animalid) to the modal? I have it kind of working but the modal will load the same id in each modal popup. See my php foreach code below and also part of the modal.

$pdo2 = Database::connect();
               $sql2 = 'SELECT * FROM animals WHERE riderid = '.$data[id].' AND hp != "Choose One"';
               foreach ($pdo2->query($sql2) as $row) {
                        echo '<tr>';
                        echo '<td>'. $row['hp'] . '</td>';
                        echo '<td>'. $row['hpname'] . '</td>';
                        echo '<td>'. $row['hpage'] . '</td>';
                        echo '<td>'. $row['hpcolour'] . '</td>';
                        echo '<td>'. $row['hpmicro'] . '</td>';
                        echo '<td>';
                        echo '<button class="btn btn-default btn-xs" id="float-right" data-toggle="modal" data-target=".bs-example-modal-lg-2"><span class="glyphicon glyphicon-pencil"></span> Update</button>';
                        echo ' ';
                        echo '<a class="btn btn-default btn-xs" href="#"><span class="glyphicon glyphicon-trash"></span> Delete</a>';
                        echo '</td>';
                        echo '</tr>';
                        $animalid = $row['id'];
               }

               Database::disconnect();
              ?>

Modal Code

<div class="modal-body">




        <form name="editanimal" id="editanimal" class="form-horizontal" action="updateanimal.php" method="post">

        <span class="form-break">

        <?php 
        // Get Animal id
        //$animalid = $data['id'];
        echo $animalid;
        ?>

$animalid is in the loop. If you want to use that value, you can store the data to other array and use it. Hope you get some inspiration.

PHP:

<?php
$pdo2 = Database::connect();
$sql2 = 'SELECT * FROM animals WHERE riderid = '.$data[id].' AND hp != "Choose One"';

$list = array();

foreach ($pdo2->query($sql2) as $row) {

  $item = array();

  $content = '<tr>';
  $content .= '<td>'. $row['hp'] . '</td>';
  $content .= '<td>'. $row['hpname'] . '</td>';
  $content .= '<td>'. $row['hpage'] . '</td>';
  $content .= '<td>'. $row['hpcolour'] . '</td>';
  $content .= '<td>'. $row['hpmicro'] . '</td>';
  $content .= '<td>';
  $content .= '<button class="btn btn-default btn-xs" id="float-right" data-toggle="modal" data-target=".bs-example-modal-lg-2"><span class="glyphicon glyphicon-pencil"></span> Update</button>';
  $content .= ' ';
  $content .= '<a class="btn btn-default btn-xs" href="#"><span class="glyphicon glyphicon-trash"></span> Delete</a>';
  $content .= '</td>';
  $content .= '</tr>';

  $item['id'] = $row['id'];
  $item['content'] = $content;

  $list[] = $item;

}

Database::disconnect();
?>

HTML:

<div class="modal-body">
  <form name="editanimal" id="editanimal" class="form-horizontal" action="updateanimal.php" method="post">
    <span class="form-break"></span>
    <?php foreach($list as $item){ ?>
      <?php echo $item['id'];?>
    <?php } ?>
    or..
    <table>
      <?php foreach($list as $item){ ?>
          <?php echo $item['content'];?>
      <?php } ?>
    </table>
    <!-- ... -->
  </form>
</div>

$animalid is being over written each time you iterate through the foreach loop. You would have to build an array to hold all of the animalids, and pass that to your modal or print out the id as you are iterating through the loop.
