CodeIgniter Form Validaton + JS. Form re-population.
- by solefald
Hello.
I have a from with a checkbox, and depending on the checkbox state 2 different divs are shown.
var alias = document.getElementById('alias');
var list = document.getElementById('list');
if(document.getElementById('isList').checked)
{
alias.style.display = 'none';
list.style.display = 'table-row';
} else {
alias.style.display = 'table-row';
list.style.display = 'none';
}
Here is the HTML/PHP (relevant) part:
<tr id="alias" style="display:table-row;">
<td>' . form_label('Destination:', 'destination') . '</td>
<td>' . form_textarea('destination') . '</td>
</tr>
<tr id="list" style="display:none;">
<td>' . form_label('File Path:', 'list_path') . '</td>
<td>' . form_input('list_path') . '</td>
</tr>
alias div is shown by default on page load, list shown then i click on isList checkbox, and alias is shown again when i click on the checkbox again.
This part works great and pretty straight froward.
Now, I add CodeIgniter Form Validation plugin, set appropriate rules and set-up validation plugin to re-populate the form with.
Without checkbox enabled everything works great. On errors form is re-populated.
However, when form is submitted with checkbox enabled, I have an issue.
CI's Form Validation plugin re-populates the form, and re-enables the checkbox,
but the list div that is supposed to be shown when checkbox enabled is not there,
and instead the alias div is shown.
Is there any way around this issue? Can i have the list div shown on list validation error?
Also, i would like to avoid using JavaScript form validation, and stick with my good old PHP.
Thank you in advance.
