Using 2 arrays at the same time in a foreach

[drisate]

Hey guys i am trying to get 2 form arrays tot to work at the same time in a foreach. I tryed a few things but nothing is working.

 

foreach ($_POST["mp3"] as $mp3 and $_POST["nom"] as $nom) {

foreach ($_POST["mp3"] as $mp3, $_POST["nom"] as $nom) {

I don't think it can be done this way. However, if both $_POST arrays have same number of elements, you can use something like this:

<?php
foreach ($_POST["mp3"] as $i=>$mp3)
{
  $nom = $_POST["nom"][$i];
  // do stuff with $mp3 and $nom
}
?>

If we saw the key structure we could probably give you a 'better' way to do it.

Yeah let me show you the complete script

 

First i have the HTML forme. It's a Javascript that generates the feilds when pressing the add button

function add_mp3_form($oups, $id){include("config.php");

print ("<tr>
            <td width='33%'><font size='1' face='Verdana' color='#F9B324'>Ajouter 
		des MP3</font></td>
            <td width='33%' align='center'><b><font face='Verdana' size='1' color='#F9B324'></font></b></td>
            <td width='33%' align='right'><font face='Verdana' size='1' color='#F9B324'>Profile d'album</font></td>
          </tr>
        </table>
        </td>
      </tr>
      <tr>
        <td width='100%' bgcolor='#55BCEA' height='7'></td>
      </tr>
      <tr>
        <td width='100%' bgcolor='#C1CDDA'>
        <table border='0' cellpadding='3' cellspacing='3' style='border-collapse: collapse' bordercolor='#111111' width='100%' id='AutoNumber4'>
          <tr>
            <td width='100%'>
		            <table border='0' cellpadding='0' cellspacing='0' style='border-collapse: collapse' bordercolor='#111111' width='602' id='AutoNumber6' height='22'><form name='etape3' method='POST' action='catalogue.php?mod=13&id=$id&send=1' enctype='multipart/form-data'>
              <tr>
                <td width='602' height='22' colspan='2'>
			<font face='Verdana' size='1' color='#FF0000'>$oups</font></td>
              </tr><tr>
                <td width='20%' colspan='2' height='22'>");  
?>
<script type="text/javascript">
var fields;

function HTMLBlock(el) {
var instance = 1, elementNames = [], i, item, container;

/* remove source element */
container = el.parentNode;
container.removeChild(el);

/* cache input elements' name attributes */
for (i = 0; item =
el.getElementsByTagName("input").item(i); i++) {
elementNames[i] = item.getAttributeNode("name");
}

/* method to modify and insert a clone of the original element */
this.insert = function () {
for (var i = elementNames.length; i--; ) {
/* replace digits with instance # */
elementNames[i].nodeValue =
elementNames[i].nodeValue.replace(/\d+/, instance);
}
instance++;
container.appendChild(el.cloneNode(true));
};
}

function createHTMLBlock(id) {
var d = document, el;

/* test browser supports the methods we'll be using */
if (d.getElementById && (el = d.getElementById(id)) &&
el.getElementsByTagName && el.cloneNode &&
el.getAttributeNode) {
/* ... etc. */
return new HTMLBlock(el); // yes
}
return null; // no
}

function addHTML() {
if (fields) {
fields.insert();
}
}
</script>

<center><input type="button" onclick="addHTML()" value="Add Fields"></center><br>

<div id="new_link_fields"><div id="form_source"><span class="r">Nom: <input type='text' name='nom[]' value='' size='20'><input type='hidden' name='i[]' value='1'> <input type='file' name='mp3[]' size='30'><br></span></div></div>

<script type="text/javascript">
/* remove the HTML and set up the object down here, before
anything's displayed */
fields = createHTMLBlock("form_source");
</script>

<?php				            
		  
            print ("</td>
              </tr></table>
            </td>
          </tr>
        </table>
        </td>
      </tr>
      <tr>
        <td width='100%' bgcolor='#C1CDDA'>
        <table border='0' cellpadding='3' cellspacing='3' style='border-collapse: collapse' bordercolor='#111111' width='100%' id='AutoNumber5'>
          <tr>
            <td width='100%'>
            <input type='submit' value='Suivant' name='btn_name3' style='float: right'></td></form>
          </tr>
        </table>
        </td>
      </tr>");		
}

 

And this is the PHP code that takes the result in charge

foreach ($_POST["mp3"] as $i=>$mp3)
{
  $nom = $_POST["nom"][$i];

// Debug line
//echo "We are taking care of $nb loops";

$file_name = $mp3['name'];
$file_tmp = $mp3['tmp_name'];

echo "<br><br><b>This is loop $i</b><br>"; 
echo "<b>The name of the file is $file_name</b><br>";	
echo "<b>The var is mp3_$i</b><br><br>";
  
//Ici je regarde si l'extantion du code est autoriser
$ext = strrchr($mp3['name'],'.');
if (($extlimit == "OUI") && (!in_array($ext,$limitedext))) {
echo "Le MP3 num $i n'a pas un extension autoriser. (mp3 seulement)<br>";
}else{

// Ici je regarde si le fichier existe déjà.
if(file_exists($upload_dir.$mp3['name'])){
$random_digit=rand(0000,9999)."_";
}else{unset($random_digit);}

if (move_uploaded_file($file_tmp,$_SERVER['DOCUMENT_ROOT']."/admin/site/".$upload_dir.$random_digit.$mp3['name'])){

chmod($_SERVER['DOCUMENT_ROOT']."/admin/site/".$upload_dir.$random_digit.$mp3['name'], 0755);   
$mp3 = new mp3($upload_dir.$random_digit.$mp3['name']);
$mp3_1 = $mp3->extract(0,30);
$newname=rand("100000", "999999")."_";
$mp3_1->save($upload_demo_dir.$newname.$random_digit.$mp3['name']);

$insert=mysql_query("INSERT INTO `distadp_adpsite`.`artiste_mp3` (id, nom_mp3, nom_demo, num_albume, nom)VALUES (NULL , '".$random_digit.$mp3['name']."', '".$newname.$random_digit.$mp3['name']."', '$_GET[id]', '$nom')");

echo "<br>MP3 numéro $i uploadé! (<a href='http://distributionadp.info/admin/site/$upload_dir$random_digit".$mp3['name']."'>".$mp3['name']."</a>)<br>";
echo "Démo de 30 sec créé avec succès! (<a href='http://distributionadp.info/admin/site/$upload_demo_dir$newname$random_digit".$mp3['name']."'>$newname".$mp3['name']."</a>)<br><br>";

}else{
echo "Il ya eu une éreure inconnu dans le transfère du fichier du mp3 num $i (".$mp3['name'].")<br>";
}
}
}

print ('<embed hidden=true loop=false src="http://distributionadp.info/s.mp3"></embed>

<meta http-equiv="refresh" content="10;url=http://distributionadp.info/admin/site/catalogue.php?mod=12&id='.$_GET[id].'">


          </td>
          </tr>
        </table>
        </td>
      </tr>');

}else{
add_mp3_form($err, $_GET[id]);
}
}

 

The current foeach sugested returns and error
