我的foreach php / MySQL代码出了什么问题？

Question

I tried to insert multiple rows from one form using checkboxes, include take values from input box, all of them has the structure:

<input id="Valor" type="text" name="Valor[]" value="<?php echo $row2["Valor"];  ?>" />

and the checkbox is like:

<input type="checkbox" name="Pago[]" id="Pago" value="<?php echo $row2["IdSolicitudTarjeta"]; ?>" />

But when I'll send the form at 'insertmultiple.php' I use the following code but only shows 2 results. Don't matter how many times I tried show the rest, don't works:

foreach($_POST['Pago'] as key => $val) {
$Producto = $_POST['Producto'][$key];
$FormaPago = $_POST['FormaPago'][$key];
$FechaConsignacion = $_POST['FechaConsignacion'][$key];
$Valor = $_POST['Valor'][$key];
$Detalle = $_POST['Detalle'][$key];
$FechaRegistrar = $_POST['FechaRegistrar'][$key];

echo $Pago." -- ".$FechaConsignacion." -- ".$Producto." -- ";
echo $FormaPago." -- ".$Valor." -- ".$Detalle." -- ";
echo $FechaRegistrar."<br>";

}

please help! :(

Answer 1

First thing: not key but $key

foreach($_POST['Pago'] as $key => $val) {

I dont see any SQL code though.

Hm... it seems like a really messy way to insert things into database. As Cyclone noticed you do not purify your input prior to inserting the date. This is wrong but its a story for another post :p

Besides consider one thing:

Are you sure you want to use

$Producto = $_POST['Producto'][$key];

and not:

$Producto = $_POST['Producto'][$val];

You seem to store some id in those checkboxes... otherwise you may have a scenario like:

1  [x]
2  [ ]
3  [ ]
4  [x]

So I blieve that $_POST['Pago'] will have only 2 fields 1 and 4... but their key will be 1 and 2 as inactive checkboxes will not have value and will not end-up in the array. I may be wrong though... shame to admit I do not remember how it works precisely Oo

Answer 2

The problem is solved, thanks for your help!!!!!, that's work with the next changes:

if(!empty($_POST['Pago'])) {
    $aLista = array_keys($_POST['Pago']);
    $Valor = $_POST['Valor'];
    $Pago = $_POST['Pago'];
    $Producto = $_POST['Producto'];
    $FormaPago = $_POST['FormaPago'];
    $FechaConsignacion = $_POST['FechaConsignacion'];
    $Detalle = $_POST['Detalle'];
    $FechaRegistrar = $_POST['FechaRegistrar'];
foreach($aLista as $key => $val) {
      print "$aLista[$key] => $val";
      echo "  ------  ";
      print "$Valor[$val]";
      echo "  ------  ";
      print "$Producto[$val]";
      echo "  ------  ";
      print "$FormaPago[$val]";
      echo "  ------  ";
      print "$FechaConsignacion[$val]";
      echo "  ------  ";
      print "$Detalle[$val]";
      echo "  ------  ";
      print "$FechaRegistrar[$val]";
      echo "<br><hr>";
}
unset($val);

}

I guess, now I can Insert that rows without problems,
