ckbox cked based on var

[ebolisa]

Hi,

I'm trying to check a box in a form based on the $status variable read from a json file. If it's a 1 then the checkbox is checked, otherwise not.

If I check/uncheck it, then the $status is written back to the json file. It's a rather simple code but I just cannot get it right.

I appreciate any help.

TIA

 

<div class="field">
  <?php
  if ($status == 1){
  $checked = "checked";
  }
  echo '<input name="ck1" type="checkbox" value='.$status.' '.$checked.' >';
  ?>                     
  <label for="ck1">Active</label>
  <!-- <input name='ck1' type='checkbox' <? if $status : "checked" ?> value = "<?=$status ?>" /> -->
  </div>

The code could use some improvement but it should work. Have you done a View Source of the page to make sure the HTML being outputted is correct? Does "cannot get it right" mean anything more than just the checkbox remaining unchecked?

[ebolisa]

Yes, remains unchecked. It always sends out 0 instead of 1 when checked.

I noticed that the double quotes remain around the word checked. Is I remove them, it works.

What is the HTML outputted, both when it didn't work and after your change that made it work?

[ebolisa]

Modified a bit the code but still no avail...

<?php
   if ($status == 1){
   echo '<input name="ck1" type="checkbox" value='.$status.' checked >';
   }
   else {
   echo '<input name="ck1" type="checkbox" value='.$status.' >';
   }
?>

The html output is this...

<div class="field">
 <label for="ck1">Activa</label>
 <input name="ck1" type="checkbox" value=0 > 
</div>

What that html will do is return a 0 when the box is checked.  It returns nothing at all if it is not checked.  In fact the $_POST array will not have an element named 'ck1' in it unless the box is checked.

As for returning a different value, perhaps you should be using a pair of radio buttons instead of a checkbox.

Ok, so how do I include an If statement within a form code?

[ginerjm]

You don't.   An if statement is not html.  Form code is.  ??  What are you talking about?

[ebolisa]

In my first post you can see the php If statement within the form code.

Ok, found the solution.

Thank you.

<div class="field">
<label for="ck1">Activa</label>
<input name="ck1" type="checkbox" value = 1 <?php echo ($status=="1" ? 'checked' : '');?> />
</div>
