Getting a var in a URL

[pavmoxo]

Hi!!!

I have a problem with getting a variable if I try to insert a new subcategory:

<? if ($_POST["nova_subcat"] != "Nova...") {?> 
                   
                  <select name="subcat_ID" id="subcat_ID" tabindex="3"> 
                                <? 
                                    $sql = "select s.subcat_ID, s.subcat_nome, c.cat_nome from subcat_links s, cat_links c where s.cat_ID=c.cat_ID and c.cat_ID=".$_GET["cat"]." order by s.subcat_nome" ; 
                                    $queryl = query($sql); 
                                    $contal = mysql_num_rows($queryl); 
                                    for ($j=0;$j<$contal;$j++) 
                                    { 
                                        $arrl = mysql_fetch_array($queryl); 
                                ?>         
                                         
                                          <option value="<?php echo $arrl["subcat_ID"]; ?>"><?php echo $arrl["subcat_nome"]; ?></option> 
                                   <? } ?>     
     
                    </select> 
                       
                                    <input name="nova_subcat" type="submit" value="Nova..."> 
                                    <input name="del_subcat" type="submit" value="Apagar">  
                     <? } else { ?> 
                            <input name="subcat_nome" type="text" class="frm1" id="subcat_nome" size="10">                      
                            <input name="insert_subcat" type="submit" value="Inserir"> 
                    <? } ?>

URL before I click Nova...

...links.php?cat=16

After:

...links.php

Beginning of the form:

<form action="links.php" method="post" enctype="multipart/form-data" name="links">

Function to insert a new subcategory:

if ($_POST["insert_subcat"] == "Inserir") 
    { 
                $sql = "insert into subcat_links values(NULL,'".$_POST["subcat_nome"]."', '".$_POST["cat_ID"]."')"; 
                $query = query($sql); 
                if ($query == 1) 
                { 
                    echo "<script>alert('A subcategoria foi introduzida com sucesso.');</script>"; 
                    echo "<meta http-equiv=\"refresh\" content=\"0;URL=links.php?cat=".$_POST["cat_ID"]."\">"; 
                } 
                else 
                { 
                    echo "<script>alert('Problemas na inserção da subcategoria.');</script>"; 
                    echo "<meta http-equiv=\"refresh\" content=\"0;URL=links.php?cat=".$_POST["cat_ID"]."\">"; 
                } 
    } 

What should I do to remain with the URL for insert a subcategory??

try putting a hidden field in and carry the value that way so use the $_POST instead e.g

<input type=hidden value=<yourvaluehere> name=subcatergory >

you mite want to do some conditioning here befor you do the header
e.g

<? if($_POST['subcatergory']) {
header("location: links.php?sub=$_POST['subcatergory']"); } else { exit; } ?>
