Update several records with a foreach - php

Question

I have a problem with a part of the code in which, through a foreach I go through an array and those that meet certain conditions are updated by an UPDATE value. The problem is that I try to pass the values ​​with a hidden input and only update the last value. How can I modify the code so I can do it with arrays?
try {
$add = "UPDATE calculo SET puntaje_fecha=:puntaje_fecha WHERE id_calculo=:id_calculo";
$d = $conn->prepare($add);
$d->bindParam(':puntaje_fecha', $_POST['puntaje_fecha']);
$d->bindParam(':id_calculo', $_POST['id_calculo']);
$d->execute();
} catch (PDOException $e) {
die("Error: " . $e->getMessage() . "<br>on line: " . $e->getLine() . "<br>on file: " . $e->getFile());
}
<form action="actualizar.php" method="post">
<?php foreach ($ca as $c){?>
<?php foreach ($pr as $p) {}?>
<?php if (($p['id_fecha'])==($c['nFecha'])){
//actions to be taken if the conditions are met
}?>
<input type="hidden" name="puntaje_fecha" value="<?php echo $s; ?>">
<input type="hidden" name="id_calculo" value="<?php echo $c['id_calculo']; ?>">
<?php }} ?>
<input type="submit" value="Actualiza puntos">
</form>
What I need is that in my "calculo" table all the values ​​of "puntaje_fecha" are updated as long as they meet that condition. Many people have recommended me to change the name of the input by arrays, but I do not know how to do it. Thank you very much to anyone who can help me.

Answer 1

You are creating only two inputs with the names of "puntaje_fecha" and "id_calculo".
So value from last iteration is posted, in order to post all values change the hidden inputs to array.
<input type="hidden" name="puntaje_fecha[]" value="<?php echo $s; ?>">
<input type="hidden" name="id_calculo[]" value="<?php echo $c['id_calculo']; ?>">
Make sure your inputs look like below by inspect element, otherwise check your data in $ca and $pr
<input type="hidden" name="puntaje_fecha[]" value="value_1">
<input type="hidden" name="id_calculo[]" value="value_1">
<input type="hidden" name="puntaje_fecha[]" value="value_2">
<input type="hidden" name="id_calculo[]" value="value_2">
<input type="hidden" name="puntaje_fecha[]" value="value_3">
<input type="hidden" name="id_calculo[]" value="value_3">
In your try block through foreach update each value in array.
try {
$puntaje_fechaArray = $_POST['puntaje_fecha'];
$id_calculoArray = $_POST['id_calculo'];
foreach ($puntaje_fechaArray as $key => $val){
$puntaje_fecha = $val[$key];
$id_calculo = $id_calculoArray[$key];
$add = "UPDATE calculo SET puntaje_fecha=:puntaje_fecha WHERE id_calculo=:id_calculo";
$d = $conn->prepare($add);
$d->bindParam(':puntaje_fecha', $puntaje_fecha );
$d->bindParam(':id_calculo', $id_calculo);
$d->execute();
}
} catch (PDOException $e) {
die("Error: " . $e->getMessage() . "<br>on line: " . $e->getLine() . "<br>on file: " . $e->getFile());
}

You can change your below code
<input type="hidden" name="puntaje_fecha" value="<?php echo $s; ?>">
<input type="hidden" name="id_calculo" value="<?php echo $c['id_calculo']; ?>">
for this:
<input type="hidden" name="puntaje_fecha[]" value="<?php echo $s; ?>">
<input type="hidden" name="id_calculo[]" value="<?php echo $c['id_calculo']; ?>">
The above treats the input forms as an array so in your controller get the data as follows:
$puntajes = $_POST["puntaje_fecha"]; //array
$idsCalculo = $_POST["id_calculo"]; //array
You can build the query with a simple foreach:
foreach($puntajes as $index => $puntaje) {
updateData($puntaje, $idsCalculo[$index]); // call the new function for update
}
function updateData($puntaje, $idCalculo) {
$add = "UPDATE calculo SET puntaje_fecha=:puntaje_fecha WHERE id_calculo=:id_calculo";
$d = $conn->prepare($add);
$d->bindParam(':puntaje_fecha', $puntaje);
$d->bindParam(':id_calculo', $idCalculo);
$d->execute();
$message = '';
if ($d->execute()) {
$message = 'DATOS ACTUALIZADOS';
} else {
$message = 'ERROR DE ACTUALIZACION';
}
} catch (PDOException $e) {
die("Error: " . $e->getMessage() . "<br>on line: " . $e->getLine() . "<br>on file: " . $e->getFile());
}
}
I hope I've helped
