I'm trying to submit multiple buttons and use them as range selectors.
Inpage1.php I have$array of years1980, 1990, 2000, 2010, ... which range is updated by database content:
<form method="post" action="page2.php">
<?php
foreach ($array as $item) {
?>
<input type="submit" name="<?= $item ?> " class="button" value="<?= $item ?> " />
<?php
}
?>
</form>
this way I can't click two buttons one after another to set the range, for example from 2000 to 2010, and submit only after this action.
I've tried JavaScript function withonclick without thepost method, which counts clicks and pushes two (first and second) clicks values as range to the resettable$rangeval array beforeif (count == 2) condition comes true, passing values to secondJavaScript functionrequest(input) frompage1.php usingajax, requestingpage2.php withif (isset($_POST['val1']) && isset($_POST['val2'])) andecho json_encode($array);, which returns an array as theresult variable withJSON.parse(res) back topage1.php.
As PHP runs on the server, I can't process theJavaScriptAjax response array asPHP array inpage1.php.
So, I'm trying to find some correct method to archive this result.
Any advice, guide, or example would be useful.
Buttons in a form and withtype="submit" will immediately submit the form. So buttons are not the correct candidate here.
I would recommend using two<select> elements where in you loop over the$array to create the options.
<form method="post" action="page2.php">
<select name="range_start">
<?php foreach ($array as $item) : ?>
<option value="<?= $item ?>"><?= $item ?></option>
<?php endforeach; ?>
</select>
<select name="range_end">
<?php foreach ($array as $item) : ?>
<option value="<?= $item ?>"><?= $item ?></option>
<?php endforeach; ?>
</select>
<input type="submit" class="button" value="Submit values" />
</form>
When submitting read out thename attributes that the<select> elements have in the$_POST array.
<?php
if (isset($_POST['range_start']) && isset($_POST['range_end'])) {
$range_start = $_POST['range_start'];
$range_end = $_POST['range_end'];
}
