Question

I’m trying to figure out how to add in a remember me functionality into my script with code igniter. Here’s what I”m attempting to do with the checkbox. I’m getting a syntax error for the if statment. Am I not using it correctly?

<?php echo form_label(form_checkbox( 'remember', 1, if (isset($this->input->cookie('xtrcook'))) { TRUE } ) . ' Auto-login in future.', 'remember' ); ?>

You have a syntax error because you’re trying to pass this as an argument:

if (isset($this->input->cookie('xtrcook'))) { TRUE }

That’s not how expressions work in PHP. You want this to be TRUE is the xtrcook cookie is set, so just pass in this:

isset($this->input->cookie('xtrcook'))

Actually, $this->input->cookie() returns either the cookie value or FALSE, and both are always “set” so isset() is not appropriate here, you can use ! empty() or !== FALSE instead:

$this->input->cookie('xtrcook') !== FALSE // evals to TRUE if the cookie exists

The whole thing:

<?php echo form_label(form_checkbox('remember', 1, $this->input->cookie('xtrcook') !== FALSE).' Auto-login in future.', 'remember'); ?>

It is a bit complicated still, might be easier to pass on the form_label() function and just write this:

<label>
    <?php echo form_checkbox('remember', 1, $this->input->cookie('xtrcook') !== FALSE); ?>
    Auto-login in future
</label>
