Javascript error ?

[Deleted member 10469]

Hello, I apply this tutorial locally:
http://xenforo.com/community/resour...he-database-with-a-page.328/update?update=475

And I have an error:

This pas and submition is O.K.

But...

Page read ==> error:

    <li id="read" class="profileContent" data-loadUrl="{xen:link downloadmanager/read}">
        <span class="jsOnly">{xen:phrase loading}...</span>
    </li>

A solution please ?
My error or wamp error please ?

There's a template error, according to that output.

It says: Invalid argument supplied for foreach().

It's a template error so the suspect code is likely to be:

<xen:foreach loop="$simpleText" value="$text">

This would indicate that either $simpleText is not an array, or that the $simpleText parameter isn't available in the template.

Hmm, I'm not supposed to have variable SimpleText, I rename all, is it possible that this is a caching problem that stock a misnamed variable?

In your error message xenforo tries to render a simpleText variable. I'd check your templates after this variable, just search in acp>templates>search templates for "simpleText". It is possible that you renamed it in your php files, but there is a template left with this variable.

Thanks, this is corrected by cons I still have the same error and when I submit the form, it tells me:
Security error occurred. Please press back, refresh the page, and try again.

Is it normal XenForo gives no indication about the error?

 

[Bob]

You need this in your form.

<input type="hidden" name="_xfToken" value="{$visitor.csrf_token_page}" />

 

[Marcus]

The <input type="hidden" name="_xfToken" value="... is missing in your <form>

Thanks, submit is ok

But I have also the error from page read:

It'll take me to training, learning frameworks it is a big advantage to encode in XenForo ?

 

[Deleted member 10469]

It's good, I have rename

<xen:foreach loop="$downloadManager" value="$text">
in
<xen:foreach loop="$downloadmanager" value="$text">

thank you for your help.
Parcontre have tips or tricks you need to give me please? I started completely, this is my first addon that uses POO.
