PHP: Confirmation Dialog without using JavaScript? - php

Question

I have a very simple form:
<form action="system/web/push.php" method="post">
<div class="row">
<div class="col card_input_push card_input_push_language">
<select name="<?php echo PARAM_PUSH_LANGUAGE; ?>">
<?php echo get_languages($mysqli); ?>
</select>
</div>
</div>
<div class="row">
<div class="col card_input card_input_push">
<input type="text" name="<?php echo PARAM_PUSH_TITLE; ?>" placeholder="<?php echo $language_array[LV_PUSH_INPUT_TITLE]; ?>"<?php echo set_value(PARAM_PUSH_TITLE); ?>required/>
</div>
</div>
<div class="row">
<div class="col card_input_push card_input_push_message">
<textarea name="<?php echo PARAM_PUSH_MESSAGE; ?>" placeholder="<?php echo $language_array[LV_PUSH_INPUT_MESSAGE]; ?>"<?php echo set_value(PARAM_PUSH_MESSAGE); ?>required></textarea>
</div>
</div>
<div class="row">
<div class="col text-center card_input_push card_button_push_send">
<button class="btn btn-default" type="submit" name="<?php echo REQUEST_SEND_GCM; ?>" value="<?php echo $language_array[LV_PUSH_INPUT_SEND]; ?>"><?php echo $language_array[LV_PUSH_INPUT_SEND]; ?></button>
</div>
</div>
</form>
When i now press the submit button i dont want the post to perform instantly. I first want a confirmation dialog to show up with yes or no answers and only if the user says yes i want the post action to be performed.
What i NOT want is to use JavaScript. Is there a way to do that?
EDIT
Thank's for the answers. To satisfy all respondents i would like to tell you, why i dont want to use JavaScript. The answer is simple. I have no idea about JavaScript. I never have used it before but the project im working on (as always) has to be finished ASAP. That's the only reason.

Answer 1

Yes there is a way, use GET (not POST) the first time, on the PHP file check if GET was used and if so generate a form that sends confirmation form back to the user. Then make confirmation form to submit using POST and you are done.
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
// generate confirmation form
}elseif ($_SERVER['REQUEST_METHOD'] === 'POST') {
// process your data
}
If anyone has access to a book called Head First PHP-MySQL they cover a similar example on page 280.

Answer 2

Maybe you could do something like this, with some css for design your dialog.
change your form with :
<form action="this_page">
If you submit, you call this page, display the dialog with a form, and when you submit with second form, you post to your needed php file.
if (isset($_POST['your_submit'] )) {
echo "<yourdialog>";
echo "<form action="system/web/push.php">";
echo "content";
echo "<submit yes>";
echo "</form>";
echo "</yourdialog>";
}

Answer 3

Your workflow is:
gather form data
send to server
get confirmation that that's what the user wants.
if yes then process data.
If you want to do that all via php then the server's handling the full load, so you'll want two forms, one to collect and one to confirm. And you'll want to store the first form's data so you can process it according to the second form's result. A bit old fashioned but not difficult.
