Joomla loginform gives 500 error on bad attempt - joomla

Question

At http://falkotl76.seventysix.axc.nl/youcollect/nl/inloggen I have a joomla loginform as a menu-item and it shows well.
When I make an attempt to login without any details it gives me a 500error and I cant figure out how to solve that.
Does anybody know how I can solve this ?
Thanks in regards,
Falko

Answer 1

Once I had the same issue and I fixed it by giving write permission to error.php file.
Path is - your joomla folder/log/error.php
Also make sure log and tmp path is correct in configuration.php

You need to load the client side validation javascript library. Create a template override for the com_users login view file default_login.php. At the top, add the JHtml::_('behavior.formvalidation'); line to load the library. And then add the class 'form-validate' to the form element. Below is an example:
defined('_JEXEC') or die;
JHtml::_('behavior.keepalive');
JHtml::_('behavior.formvalidation');
?>
<div class="login<?php echo $this->pageclass_sfx?>">
<?php if ($this->params->get('show_page_heading')) : ?>
<h1>
<?php echo $this->escape($this->params->get('page_heading')); ?>
</h1>
<?php endif; ?>
<?php if (($this->params->get('logindescription_show') == 1 && str_replace(' ', '', $this->params->get('login_description')) != '') || $this->params->get('login_image') != '') : ?>
<div class="login-description">
<?php endif ; ?>
<?php if($this->params->get('logindescription_show') == 1) : ?>
<?php echo $this->params->get('login_description'); ?>
<?php endif; ?>
<?php if (($this->params->get('login_image')!='')) :?>
<img src="<?php echo $this->escape($this->params->get('login_image')); ?>" class="login-image" alt="<?php echo JTEXT::_('COM_USER_LOGIN_IMAGE_ALT')?>"/>
<?php endif; ?>
<?php if (($this->params->get('logindescription_show') == 1 && str_replace(' ', '', $this->params->get('login_description')) != '') || $this->params->get('login_image') != '') : ?>
</div>
<?php endif ; ?>
<form action="<?php echo JRoute::_('index.php?option=com_users&task=user.login'); ?>" method="post" class="form-validate">
<fieldset>
<?php foreach ($this->form->getFieldset('credentials') as $field): ?>
<?php if (!$field->hidden): ?>
<div class="login-fields"><?php echo $field->label; ?>
<?php echo $field->input; ?></div>
<?php endif; ?>
<?php endforeach; ?>
<?php if (JPluginHelper::isEnabled('system', 'remember')) : ?>
<div class="login-fields">
<label id="remember-lbl" for="remember"><?php echo JText::_('JGLOBAL_REMEMBER_ME') ?></label>
<input id="remember" type="checkbox" name="remember" class="inputbox" value="yes" alt="<?php echo JText::_('JGLOBAL_REMEMBER_ME') ?>" />
</div>
<?php endif; ?>
<button type="submit" class="button"><?php echo JText::_('JLOGIN'); ?></button>
<input type="hidden" name="return" value="<?php echo base64_encode($this->params->get('login_redirect_url', $this->form->getValue('return'))); ?>" />
<?php echo JHtml::_('form.token'); ?>
</fieldset>
</form>
</div>
<div>
<ul>
<li>
<a href="<?php echo JRoute::_('index.php?option=com_users&view=reset'); ?>">
<?php echo JText::_('COM_USERS_LOGIN_RESET'); ?></a>
</li>
<li>
<a href="<?php echo JRoute::_('index.php?option=com_users&view=remind'); ?>">
<?php echo JText::_('COM_USERS_LOGIN_REMIND'); ?></a>
</li>
<?php
$usersConfig = JComponentHelper::getParams('com_users');
if ($usersConfig->get('allowUserRegistration')) : ?>
<li>
<a href="<?php echo JRoute::_('index.php?option=com_users&view=registration'); ?>">
<?php echo JText::_('COM_USERS_LOGIN_REGISTER'); ?></a>
</li>
<?php endif; ?>
</ul>
</div>
I added a couple of links of template overrides for reference. This should solve your issue.
