I want to force my site to refresh the captcha image everytime it loads,

  • 0

I want to force my site to refresh the captcha image everytime it loads, so I have a javascript method triggered with the onload() event. Here I have the following line:

document.getElementById('yw0_button').click;

Firebug doesn’t detect any errors, and for testing purposes I have added an alert right after the displayed line, and the alert pops up each time the page is loaded. However, the image doesn’t refresh!

This is what I believe is relevant about the view file:

<?php if(extension_loaded('gd')): ?>
    <div class="row">
        <?php echo $form->labelEx($model,'verifyCode'); ?>
        <div>
            <?php
            $this->widget('CCaptcha',
                          array('showRefreshButton'=>true,
                                'buttonType'=>'button',
                                'buttonOptions'=>
                                                    array('type'=>'image',
                                                          'src'=>"/path/images/refresh-icon.png",
                                                          'width'=>30,
                                                    ),                                                            
                                'buttonLabel'=>'Refrescar imagen'),
                          false); 
            ?>
            <br>
            <?php echo $form->textField($model,'verifyCode'); ?>
        </div>
    <div class="hint">
        Porfavor ingrese las letras como las ve en la imagen superior.
        <br/>No hay distincion entre minúsculas y mayúsculas.</div>
    </div>
<?php endif; ?>

Any ideas?

@k to the z just saw this! Yes sure, if you could help me find a more proper solution it would be awesome! This is what i believe is relevant about the view file:

<?php if(extension_loaded('gd')): ?>
        <div class="row">
            <?php echo $form->labelEx($model,'verifyCode'); ?>
            <div>
                <?php
                $this->widget('CCaptcha',
                              array('showRefreshButton'=>true,
                                    'buttonType'=>'button',
                                    'buttonOptions'=>
                                                        array('type'=>'image',
                                                              'src'=>"/path/images/refresh-icon.png",
                                                              'width'=>30,
                                                        ),                                                            
                                    'buttonLabel'=>'Refrescar imagen'),
                              false); 
                ?>
                <br>
                <?php echo $form->textField($model,'verifyCode'); ?>
            </div>
        <div class="hint">
            Porfavor ingrese las letras como las ve en la imagen superior.
            <br/>No hay distincion entre minúsculas y mayúsculas.</div>
        </div>
    <?php endif; ?>

In the controller I grant authorized users permission in the accessRules() method to the captcha action, and thats about all. Is there something else I could post?

    In case anyone goes through a similar problem whilst getting started with Yii.. This is how I resolved the CAPTCHA issue triggering a click: I have an event triggered the the onload event, which has the following code:

    $(‘#yw0_button’).click();

    There surely must be a better way, im open to suggestions! However as a temporary solution this works just fine, refreshing the captcha image each time the page is loaded. Good luck!

    EDIT: What I did was handle the onload event for my html page like this 

    <body onload="initialize()"> 
.. 
</body>

    Then in my js file:

    function initialize() 
{ 
     $('#yw0_button').click(); 
}
