You are using the fanstactic Gregwar/ImageBundle code to manipulate your images on Symfony2 and twig.
But instead of rendering your website, you get this error on your apache error log file

1
PHP Fatal error:  Method Gregwar\\ImageBundle\\ImageHandler::__toString() must not throw an exception in /home/www/recette/app/cache/dev/classes.php on line 7426

or directly on your html genered code

Fatal error: Method Gregwar\ImageBundle\ImageHandler::__toString() must not throw an exception in /home/www/recette/app/cache/dev/classes.php on line 7426

this issue may be a rights problem on your cache drectory. By default, gregwar cache directory is on your web so, launch this command

1
chmod 777 web/cache

This error may also occur if the file doesn’t exist, for a clean code, add

1

3
{% if file_exists('uploads/' ~ site.id ~ '.jpg') %}
    {{ image(site.picture).resize(250, 50) }}
{% endif %}

or on twig code

3
{% if site.has_picture %}
    {{ image(site.picture).resize(250 ,50) }}
{% endif %}

For more informations about file_exists, see here Symfony2 twig add new function file_exists

You need to enable either the SQLite3 or PDO_SQLite extension for the profiler to run properly.

After installing Symfony 2 instead of viewing your website, you see this error message :

You need to enable either the SQLite3 or PDO_SQLite extension for the profiler to run properly.

It probably means you need to install the sqlite extension for php

1
apt-get install php5-sqlite

restart apache and that should to the tricks.

Symfony 1.x propel-insert-sql [propel-sql-exec] SQLSTATE[42000]: Syntax error or access violation: 1064

You are using a old version of symfony 1.x on a new version of mysql and when you try to insert the model on your database you get this error :

[propel-sql-exec] SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘Type=InnoDB’ at line 6

The problem come from this query

CREATE TABLE `pret_externe_type`
 (
 `id_pret_externe_type` BIGINT(20)  NOT NULL AUTO_INCREMENT,
 `libelle` VARCHAR(100)  NOT NULL,
 PRIMARY KEY (`id_pret_externe_type`)
 )Type=InnoDB

Mysql do not use “Type=” option anymore, you have to replace it by “Engine=”

 )Engine=InnoDB

To fix it the code, on symfony 1.2 go on this file /lib/plugins/sfPropelPlugin/lib/vendor/propel-generator/classes/propel/engine/builder/sql/mysql/MysqlDDLBuilder.php and change the line 156
from

1
$script .= "Type=$mysqlTableType";

to

1
$script .= "Engine=$mysqlTableType";

On symfony 1.4, you have to change this file : lib/vendor/symfony/lib/plugins/sfPropelPlugin/lib/vendor/propel-generator/classes/propel/engine/builder/sql/mysql/MysqlDDLBuilder.php
Always on ligne 156

After code change, rebuild your SQL model and insert it to your databases

If you are installing a symfony 1.x project on a PHP 5.4.1 (or later) version, you may encounter this warning message :

sfWidgetFormDateJQueryUI date format

Posted on by

You want to use the sfWidgetFormDateJQueryUI widget but you cannot configure it to display the date in your culture ?

I had the same problem, and there is what I did to fix it.

I start to override the sfWidgetFormDateJQueryUI class to add a “format_date” option. Add a new class here lib/widget/adinWindgetFormDateJQueryUI.class.php and override the configure fonction to add the format_date option.

5
protected function configure($options = array(), $attributes = array())
 {
   $this->addOption('format_date', null);
   parent::configure($options, $attributes);
 }

In the render function, format the value

1

3
4
if($this->getOption('format_date') != null){
     $dateFormat = new sfDateFormat();
     $value = $dateFormat->format($value, $this->getOption('format_date'));
 }

(The complete class source is at the end of this post.)

In your formClass, configure the widget :

                      "date_output" => "Y-m-d",  //format the value after validation to send to BDD
                      "required" => true
                      )
                 );

Symfony The default context does not exist

Posted on by

You may have to use in your model class or somewhere else the “context instance” in your code but when this code is used by a task, a test or data fixture, you get a “The default contect does not exist” error.
To avoid that, you can use the sfContext::hasInstance() fonction. See below

          $this->setIdService($id_service);

You had an unbound input in your form and Symfony throw you an “unexpected extra form field named ‘yourfield'” error ?

Don’t worry, add a sfValitorPass() in your form description :

Symfony 1.4 format date doctrine object

Posted on by
Reply

To format a date from a doctrine object, you can use this code, quick and easy.

1
$demande->getDateTimeObject('date_creation')->format('d/m/Y');

Sometimes, this first solution return current date even if the doctrine record is null.
You then have to use this other solution

1
2
use_helper('Date');
format_date($demande->getDateCreation(), 'dd-MM-yyyy');

You can found format rules here

ckWebServicePlugin empty params

Posted on by

You are using Symfony and the ckWebServicePlugin but in your action method you can’t access params value ? They are desperately empty ?

This may due to a configuration issue, in your apps/config/filters.yml, it is important to put the soap_parameter before the cache and execution parameters

doesn’t work
