Question

I have web page in PHP which displays all records in a table. I want to add check boxes against all rows and user can check a check box to select a row and then submit the page. When the page is submitted I want to enumerate all check boxes and check whether they are checked or not, How can I do this?

Answer 1

Creating the form

You can generate the HTML as follows:

<form [action, method etc]>
  <table>
  <?php 
    foreach($dataSet as $dataRow) : 
  ?>
      <tr>
         <td>
            <input type="checkbox" name="dataRow[]" value="<?=$dataRow['id']?>"/>
         </td>
         [Additional details about datarow here]
      <tr>
  <?php 
    endforeach; 
  ?>
  </table>
</form>

AFTER POST

look into $_POST[‘dataRow’] : this will be an array with values the IDS of your $dataRow, so using array_values on $_POST[‘dataRow’] will give you all the ids of the selected rows:

<?php
   $checkedRows = array_values($_POST['dataRow']);
   foreach($checkedRows as $row) {
      // Do whatever you want to do with the selected row
   }
