Smarty

[Mike87]

Hello,

I am new with smarty. I have it installed on my webserver and now I receive constantly the following error in my php log file:

PHP Warning: Illegal string offset 'id' in .../smarty_internal_templatebase.php(157) : eval()'d code on line 90

I checked the file mentioned and searched for line 90 (second line of the below):

// check URL debugging control
if (!$this->smarty->debugging && $this->smarty->debugging_ctrl == 'URL') {
if (isset($_SERVER['QUERY_STRING'])) {
$_query_string = $_SERVER['QUERY_STRING'];
} else {
$_query_string = '';
}

I also checked line 157 (fourth line of the below):

if (!$_template->compiled->exists || ($_template->smarty->force_compile && !$_template->compiled->isCompiled)) {
$_template->compileTemplateSource();
$code = file_get_contents($_template->compiled->filepath);
eval("?>" . $code);
unset($code);
$_template->compiled->loaded = true;
$_template->compiled->isCompiled = true;
}

I am not a professional programmer but it would be very nice if anyone could give me a hint where to search for that mistake. I am not asking for a complete solution but at the moment I have no clue at all. It might be helpful if someone could just explain the error...

The error must be in your template source.
Line 90 is in the compiled template, however we can't see corresponding PHP source.

Do you use in your template an index or variable 'id' ?

Caching template output with unset {nocache} variables?

P.S.
@U.Tews: What is the chances for Smarty to work without eval()?

[U.Tews]

I don't think it's an unassigned variable.

Upcomming 3.1.22 will work without eval

Seriously? O.o
Cause I was considering to put eval() into disabled functions on some of the servers I manage, since their owners absolutely unable to hold their own hands straight, and I had to ditch rShell and the kind not once.
Blocking eval() and some other functions makes it at least considerable harder to break into running PHP process, as well as break out of it.

Thank you for your replies. I give my best:

Line 90 of the compiled template tpl-file:

<?php if ($_smarty_tpl->tpl_vars['ooocat']->value['id']==$_smarty_tpl->tpl_vars['parents']->value['id_category']) {?>
<?php $_smarty_tpl->tpl_vars['is_in_subcategories'] = new Smarty_variable(1, null, 0);?>
<?php }?>


I am using smarty as part of the newly installed prestashop. Do you think it is more an error in the code of prestashop rather than smarty? That would bring me already one step further.

[U.Tews]

It looks like that template variable $ooocat is not an array which has an element with index 'id', but is a string.

It's not a Smarty error.

Ok I will try to work with it further. Thank you for your help so far
