smarty plugin error

Hi,
It is my first time to use the smarty plugin for the forms generation class in my projects. However I get this error:

Fatal error: Call to a member function AddDataPart() on a non-object in ../plugins/insert.formadddatapart.php on line 18.

When I try to var_dump($tpl_vars['form']) it dumps an object.

I would appreciate any help from you people.

Regards,

It is hard to tell without seeing your code.

Maybe you are reassigning the template variable to something else that is not the form object.

Hi Manuel,

Thanks for your reply. Here is the code.

<?php

include('../setup/smarty_setup.php');
/*
* Include Smarty template prefilter plugin function
*
*/

require("plugins/prefilter.form.php");

/*
* Include form class code.
*/
require("../forms/forms.php");

/*
* Create a form object.
*/
$form=new form_class;

$form->NAME="company_form";

$form->METHOD="GET";

$form->ACTION="";

$form->ResubmitConfirmMessage="Are you sure you want to submit this form again?";

$form->OptionsSeparator="<br>\n";

/*
* Output all validation errors.
*/
$form->ShowAllErrors=1;

/*
* CSS class for invalid inputs.
*
*/
$form->InvalidCLASS='invalid';

/*
* Define the form field properties even if they may not be displayed.
*/
$form->AddInput(array(
"TYPE"=>"text",
"NAME"=>"company_name",
"ID"=>"company_name",
"MAXLENGTH"=>100,
"Capitalization"=>"lowercase",
"ValidateAsNotEmpty"=>1,
"ValidationErrorMessage"=>"Company name is required",
"LABEL"=>"<u>C</u>ompany name",
"ACCESSKEY"=>"C"
));
$form->AddInput(array(
"TYPE"=>"text",
"NAME"=>"reg_number",
"ID"=>"reg_number",
"MAXLENGTH"=>100,
"Capitalization"=>"lowercase",
"ValidateAsNotEmpty"=>1,
"ValidationErrorMessage"=>"Company registration number is required",
"LABEL"=>"<u>R</u>egistration No.",
"ACCESSKEY"=>"R"
));

$form->AddInput(array(
"TYPE"=>"hidden",
"NAME"=>"doit",
"VALUE"=>1
));

...............

/*I process form here normally */

$form->LoadInputValues($form->WasSubmitted("doit"));

$verify=array();

if($form->WasSubmitted("doit"))
{

if(($error_message=$form->Validate($verify))=="")
{
$doit=1;

}
else
{
$doit=0;
$error_message=HtmlEntities($error_message);
}
}
else
{
$error_message="";
$doit=0;
}
if($doit)
{

$form->ReadOnly=1;
}

/*
* I Create the Smarty engine object to process the form template first
*
*/

$smarty=&new EicharTemplateEngine();
if($smarty->template_exists("company_form.tpl"))
{
$smarty->assign_by_ref("form",$form);/* I assign the object here*/
$smarty->assign("title","General Company Information");
$smarty->assign("error_message",$error_message);
$smarty->assign_by_ref("verify",$verify);
$smarty->assign("doit",$doit);
$smarty->assign("mark","[Verify]");
$smarty->register_prefilter("smarty_prefilter_form");
$smarty->fetch("company_form.tpl");
$smarty->unregister_prefilter("smarty_prefilter_form");
}

........................


/*
* I Output the form within a page using a Smarty page template
*/
if($smarty->template_exists("company_info.tpl"))
{
$onload=HtmlSpecialChars($form->PageLoad());
$smarty->assign("form", $form->FetchOutput());
$smarty->assign("title", "General Company Information");
$smarty->assign("onload", $onload);
$smarty->assign('styles', '.invalid { border-color: #ff0000; background-color: #fff; }');
$smarty->display("company_info.tpl");
}
?>

And here is the template.

{include file="formerror.tpl"}
<center><table summary="Form table" border="1" bgcolor="#c0c0c0" cellpadding="2" cellspacing="1">
<tr>
<td bgcolor="#000080" style="border-style: none;"><font color="#ffffff"><b>{$title}</b></font></td>
</tr>
<tr>
<td style="border-style: none">
<center><table summary="Input fields">

<tr>
<th align="right">{label for="company_name"}:</th>
<td>{input name="company_name"}</td>
{if isset($verify.company_name)}<td>{$mark}</td>
{/if}

<th align="right">{label for="reg_number"}:</th>
<td>{input name="reg_number"}</td>
{if isset($verify.reg_number)}<td>{$mark}</td>
{/if}
</tr>
.......................

Once again the error is caught in plugins/prefilter.form.php which I have not edited.

Regards,

I could not reproduce your error because you use a different Smarty class and you used a template file that you did not provide.

Anyway, it seems the problem may be caused by the line:

$smarty->assign("form", $form->FetchOutput());

It reassigns the form template variable which would not be a problem if $smarty->unregister_prefilter("smarty_prefilter_form") was working. I don't know what changed Smarty class you are using but that may be the root of your problem.

To avoid further problems, I suggest changing the form template variable to something like company_form and change your template too.


Alternatively, since your form uses a pretty straightforward vertical layout, I suggest using the form_layout_vertical forms class plug-in. Take a look at the test_auto_layout_form.php example script.

There is an even more productive plug-in for AJAX scaffolding that was just announced to be in beta. It needs documentation but it is certainly a giant leap forward in productivity that you may want to check out.

Problem solved by the form_layout_vertical forms class plug-in
