    <p>i'm using Symfony2 + Doctrine 2</p> <p>In the validation of a dynamic form gives me this error and do not understand why. Only get error when I add one or more 'conocimiento' (Tags) to the class 'Recurso'</p> <p>I present here the corresponding classes</p> <pre><code>class Recurso { ... /** * @var TheWire\PersonaBundle\Entity\Rec_Conocimiento $conocimiento *, * @ORM\OneToMany(targetEntity="TheWire\PersonaBundle\Entity\Rec_Conocimiento", mappedBy="recurso", cascade={"all"}, orphanRemoval="true") */ private $conocimiento; ... public function __construct() { $this-&gt;conocimiento = new \Doctrine\Common\Collections\ArrayCollection(); } .... /** * Set conocimiento * * @param \TheWire\PersonaBundle\Entity\Rec_Conocimiento $conocimiento */ public function setConocimiento($conocimiento) { $this-&gt;conocimiento = $conocimiento; foreach ($conocimiento as $con){ $con-&gt;setRecurso($this); } } /** * Get conocimiento * * @return \Doctrine\Common\Collections\ArrayCollection */ public function getConocimiento() { return $this-&gt;conocimiento; } ..... </code></pre> <p>And</p> <pre><code>class Rec_Conocimiento { /** * @var integer $id * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * * @ORM\id * @ORM\ManyToOne(targetEntity="TheWire\PersonaBundle\Entity\Recurso", inversedBy="conocimiento") * @ORM\JoinColumn(name="recurso_id", referencedColumnName="id") */ private $recurso; /** * @var string $conocimiento * @ORM\Id * @ORM\ManyToOne(targetEntity="TheWire\PersonaBundle\Entity\Conocimiento") */ private $conocimiento; /** * @var smallint $nivel * * @ORM\Column(name="nivel", type="smallint") */ private $nivel; /** * Get id * * @return integer */ public function getId() { return $this-&gt;id; } /** * Set recurso * * @param \TheWire\PersonaBundle\Entity\Recurso $recurso */ public function setRecurso(\TheWire\PersonaBundle\Entity\Recurso $recurso) { $this-&gt;recurso = $recurso;

} /** * Get nivel * * @return smallint */ public function getNivel() { return $this-&gt;nivel; } ... </code></pre> <p>And class TheWire\PersonaBundle\Entity\Conocimiento is only $id and $name (Tags)</p> <p>I created the form:</p> <pre><code>class RecursoAddType extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { $builder -&gt;add('conocimiento', 'collection', array( 'required' =&gt; false, 'type' =&gt; new ConocimientoAddType(), 'allow_add' =&gt; true, 'allow_delete' =&gt; true, 'prototype' =&gt; true, // Post update 'by_reference' =&gt; false, )) ; } </code></pre> <p>and</p> <pre><code>class ConocimientoAddType extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { $builder -&gt;add('conocimiento', 'entity', array( 'required' =&gt; false, 'class' =&gt; 'TheWire\\PersonaBundle\\Entity\\Conocimiento', 'empty_value' =&gt; 'Selecciona un conocimiento', 'multiple' =&gt; false, 'query_builder' =&gt; function(EntityRepository $repositorio) { return $repositorio-&gt;createQueryBuilder('con')-&gt;leftjoin('con.bloque', 'bloque') -&gt;orderBy('bloque.descripcion, con.descripcion'); }, )) -&gt;add('nivel', null,array('required' =&gt; false, 'label' =&gt; 'Nivel: ')) ; } </code></pre> <p>I created in the controller normally, with a entity in the db and pass to Twig</p> <pre><code>$recurso = $em-&gt;getRepository('PersonaBundle:Recurso')-&gt;findOneBy(array('id' =&gt; $id)); $formularioEditarRecurso = $this-&gt;createForm(new RecursoAddType(), $recurso); </code></pre> <p>I show the form and use jquery to add more fields dynamically</p> <pre><code>&lt;script type="text/javascript"&gt; $(document).ready(function() { function add() { var collectionHolder = $('#thewire_personabundle_recursoaddtype_conocimiento'); var prototype = collectionHolder.attr('data-prototype'); form = prototype.replace(/\$\$name\$\$/g, collectionHolder.children().length); collectionHolder.append(form); } $(".record_actions").delegate("a.jslink", "click", function(event){ event.preventDefault(); add(); }); }); &lt;/script&gt; </code></pre> <p>When valid form:</p> <pre><code>if ($request-&gt;getMethod() == 'POST') { $formularioEditarRecurso-&gt;bindRequest($request); if ($formularioEditarRecurso-&gt;isValid()) { $em-&gt;persist($recurso); $em-&gt;flush(); return $this-&gt;redirect($this-&gt;generateUrl('AdminPeticionVer', array('id' =&gt; $recurso-&gt;getPeticion()-&gt;getId()))); } } </code></pre> <p>Get the error:</p> <blockquote> <p>SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens</p> </blockquote> <p>I guess this error is to send more tags of which was</p> <p>how I can prevent this error? Thanks</p>

    1. COThe error you posted usually results from an incorrectly formed prepared statement. But I don't really see where you are doing any such thing. Are you sure nothing else is going on in your script? Maybe check the sql logs.

    2. COI see this: INSERT INTO Rec_Conocimiento (recurso_id, conocimiento_id, nivel) VALUES (?, ?, ?) ({"1":2}) Only nivel, but don't recurso_id or conocimiento_id values. But they are in the form! I do not understand

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
