we want to pass php array in hidden input field from html to php. how can we pass the array from html to php
<?php
$data = array(
array("Volvo",22,18),
array("BMW",15,13),
array("Saab",5,2),
array("Land Rover",17,15)
);
?>
<form name="excel_upload" id="excel_upload" action="" method="post">
<input type="hidden" name="data[]" >
<input type="submit">
</form>
You can have multiple hidden inputs with the same name and if the name contains the brackets, PHP will parse them as an array. See this answer for more details: HTML form with multiple hidden control elements of the same name
For example:
<form name="excel_upload" id="excel_upload" action="" method="post">
<input type="hidden" name="data[]" value="Volvo" >
<input type="hidden" name="data[]" value="BMW" >
<input type="hidden" name="data[]" value="Toyota" >
<input type="submit">
</form>
<?php
$cars = array("Volvo", "BMW", "Toyota");
$cars_string = implode(',',$cars);
?>
<form name="excel_upload" id="excel_upload" action="" method="post">
<input type="hidden" name="data" value="<?php echo $cars_string?>" >
<input type="submit">
</form>
You may use implode function of PHP. To decode it at php end again use explode function of PHP
Best way to pass Array from a form is sending in serialize format.
<form name="excel_upload" id="excel_upload" action="" method="post">
<input type="hidden" name="data" value="<?php echo serialize($cars); ?>" >
<input type="submit">
</form>
Once Form Post, You can unserialize the posted value.
<?php
$data = isset($_POST['cars']) ? unserialize($_POST['cars']) : [];
?>
You can also use json_encode in place of serialize and get data by json_decode. in place of unserialize
Thanks
You can't send array as it is but you can achieve same thing using some thing like
<form name="excel_upload" id="excel_upload" action="" method="post">
<?php
$i = 1;
foreach($cars as $car){
?>
<input type="hidden" name="car<?php echo $i; ?>" value="<?php $car; ?>" >
<?php
$i++;
}
?>
<input type="submit">
</form>
You can get value on server side in same way like $_POST['car1'] etc
Try this :
<!DOCTYPE html>
<html lang="en">
<?php
$data = array(
array("Volvo", 22, 18),
array("BMW", 15, 13),
array("Saab", 5, 2),
array("Land Rover", 17, 15)
);
if (isset($_POST['submit'])) {
print_r($_POST['data']);
}
?>
<body>
<form method="post" action="">
<?php
foreach ($data as $key => $val) {
foreach ($val as $k => $v) {
?>
<input type="hidden" name="data[<?php echo $key; ?>][<?php echo $k ?>]" value="<?php echo $v; ?>">
<?php
echo "<br>";
}
}
?>
<input type="submit" name="submit">
</form>
</body>
</body>
</html>
finally after trying lot of method this one worked for me with using serialize and unseiralize.
HTML:
<input type="hidden" name="data" value="<?php echo htmlspecialchars(serialize($data)) ?>">
PHP:
$excel = unserialize($_POST["data"]);
