I know how to keep the checkboxes checked on form submit when there is

  • 0

I know how to keep the checkboxes checked on form submit when there is an error, but I have a different issue now. I am using check boxes of the same name where people can click 1 or multiple. I want it to only keep the check boxes that the user checked filled if there is a problem like if they check q1 A q1B but not q1c I want only q1 A and Q1b to show checked when reloaded on an error. Right now on an error all checkboxes of the same name are checked. I have tried changing the name to q1[] but that did not work. Can you please take a look and let me know how to fix this?

Here is my code.

    <tr>
<td style="width: 124px" class="style15">Tape Recorder<?php    if(isset($problems['tape[]'])) {?><font color="red">*</font><?php } ?></td>
<td class="style9"> 
    <input name="tape[]" id="tape1" type="checkbox" value="used before," <?php   if(isset($_POST['tape[]'])) echo "checked"; ?> 
  </td>
<td class="style9"> 
    <input name="tape[]" id="tape2" type="checkbox" value="helpful in past,"        <?php   if(isset($_POST['tape[]'])) echo "checked"; ?> </td>
<td class="style9"> 
    <input name="tape[]" id="tape3" type="checkbox" value="requesting from DACC" <?php if(isset($_POST['tape[]'])) echo "checked"; ?> </td>
<td class="style9"> 
    <input name="tape[]"  id="tape4" type="checkbox" value="NA" <?php if(isset($_POST['tape[]'])) echo "checked"; ?></td>
 </tr>
  <tr>
        <td style="width: 124px">Note Taker <?php if(isset($problems['note'])) {?>      <font color="red">*</font><?php } ?></td>
<td class="style9"> 
        <input name="note" type="checkbox" value="used before," <?php if(isset($_POST['note'])) echo "checked"; ?> 
</td>
<td class="style9"> 
    <input name="note" type="checkbox" value= "been helpful in the past," <?php if(isset($_POST['note'])) echo "checked"; ?> 
<td class="style9"> 
    <input name="note" type="checkbox" value= "requesting from DACC" <?php if(isset($_POST['note'])) echo "checked"; ?> 
<td class="style9"> 
    <input name="note" type="checkbox" value="NA" <?php if(isset($_POST['note'])) echo "checked"; ?> 
</tr>

    A quick and dirty solution would be:

    <input name="tape[]"  id="tape[]" type="checkbox" value="NA" <?php if(isset($_POST['tape']) && is_array($_POST['tape']) && in_array('NA', $_POST['tape'])) echo 'checked="checked"'; ?> />

    For that you need to change the ‘NA’ part for each different answer obviously. Though I would look at something like having a loop for repeated checkboxes or a callback function to determine whether or not to echo checked=checked.
