表单提交后的URL重定向没有继承的参数

Question

I am working on a web site using PHP and JQuery Mobile. On a page I have a form:

 <form method="post" name="form1" id="form1" onsubmit="return comprobardatos()" data-ajax="false" action="<?php echo $editFormAction; ?>">
<p>

  Nombre:
    <input type="text" name="nombre_plato" id="nombre_plato"  value="" size="32" >
<div id="mensajealias"></div><div id="ajaxBusy" style="display: none;"><p><img src="wait.gif"></p></div>
  </p>
<p>Descripción:
  <input type="text" name="descripcion_plato" id="descripción_plato" value=""  size="32"><div id="mensajenombre"></div>
  </p>

<p>Precio 1:
  <input type="text" name="precio1_plato"  value="" onkeypress="if ( isNaN(this.value + String.fromCharCode(event.keyCode) )) return false;" size="32">
  </p>
  <p>Precio 2:
  <input type="text" name="precio2_plato"  value="" onkeypress="if ( isNaN(this.value + String.fromCharCode(event.keyCode) )) return false;" size="32">
  </p>
  <p>Precio 3:
  <input type="text" name="precio3_plato"  value="" onkeypress="if ( isNaN(this.value + String.fromCharCode(event.keyCode) )) return false;" size="32">
  </p>
  <p>Precio 4:
  <input type="text" name="precio4_plato"  value="" onkeypress="if ( isNaN(this.value + String.fromCharCode(event.keyCode) )) return false;" size="32">
  </p>

<p>
  <input type="button" name="clear" data-role="button" data-theme="e" value="Limpiar formulario" onclick="clearForm(this.form);">
  <div id="boton"><input type="submit" data-role="button" data-theme="b"id="insertar" value="Insertar Nuevo Contenido de la Carta" ></div><div id="mensajeboton"></div>
</p>
<p>
          <input type="hidden" name="cadena_plato" value="<?php echo $_SESSION[Region]?>">

          <input type="hidden" name="restaurante_plato" value="<?php echo $_GET['rest']?>">

          <input type="hidden" name="categoria_plato" id="categoria_plato" value="<?php echo $_GET['cat']?>">
                <input type="hidden" name="MM_insert" value="form1">
              </p>

            </form>

The URL from the page is:

http://.../NuevoAdminPlato.php?rest=1&cat=9

When the user clicks on the submit button, the page AdminPlatos.php should be shown. This is the part of the code that I am using to go to the page>

$insertGoTo = "AdminPlatos.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $insertGoTo));
}

But the launched URL is?

http://.../AdminPlatos.php?rest=1&cat=9

And I don't want to get there the params> rest=1&cat=9

I guess this is a JQuery issue, but I don't know how to avoid it.

Answer 1

So, here you have complete block of code...

$insertGoTo = "AdminPlatos.php";
if(!empty($_POST['cat'])) {
  $insertGoTo .= '?id=something';
  $insertGoTo .= '&cat='.$_POST['cat'];
  header("Location: $insertGoTo");
}

I used !empty($_POST['cat']), because you are going to use just 'cat' and !empty() better fit than isset(), because 'cat' could be empty, but isset() would wtill return true;

Then I used header("Location: $insertGoTo");, because you have single one variable and this should be more clear to read.
