LemonStand Version 1 Has Been Discontinued

This documentation is for LemonStand Version 1. LemonStand is now offered as a cloud-based eCommerce platform.

Handling errors

Errors could occur during the form processing. When an error occurs, LemonStand places its message to the internal variable. You can use the flash_message function to display error messages. Usually you place the flash_message function call above forms.

The following example demonstrates the Change Password page.

<h2>Change Password</h2>
<?= open_form() ?>
	<?= flash_message() ?>
	<label for="old_password">Old Password</label>
	<input id="old_password" type="password" name="old_password"/><br/>
	
	<label for="password">New Password</label>
	<input id="password" type="password" name="password"/><br/>
	
	<label for="password_confirm">Password Confirmation</label>
	<input id="password_confirm" type="password" name="password_confirm"/><br/>
	
	<input type="submit" name="change_password" value="Submit"/>
	<input type="hidden" name="redirect" value="/password_change_success"/>
</form>

If you process forms in AJAX mode, you do not need to use the flash_message function, because AJAX errors are displayed using the popup messages (JavaScript alert messages).
