Closed 4 years ago.
I have a simple HTML form like this:
<form action="index.php" method="post">
<textarea id="question" name="question"></textarea>
<input type="submit"/>
</form>
And the procedure that I'd like it to be is something like described here:
Type something in the text area and click submit, result displayed:
[... the only text area got blank and be ready for new input ...]
Question 1: Something typed firstly
Type some other thing in the above text area and submit, result displayed:
[... the only text area got blank and be ready for new input ...]
Question 1: Something typed firstly
Question 2: Something typed secondly
And so on...
[... the only text area got blank and be ready for new input ...]
Question 1: Something typed firstly
Question 2: Something typed secondly
...
Question n: Something typed at the n time
Does anyone have an idea or can give me a hint how to do this using only HTML and PHP?
Thank you very much!
If you don't want to put the values in a database you could use a session
session_start();
at the very top of your page and
<?php
if( $_SESSION['counter'] > 0 ) $_SESSION['texts'] = $_SESSION['texts'] . "<br />Question " . $_SESSION['counter'] . ": Something " . $_POST['question'];
$_SESSION['counter']++;
?>
<?php echo $_SESSION['texts']; // put this in a div where you want to see them ?>
This will only clear when the browser is shut.
This is a very crude outline but you could look at tutorials on sessions and how to use them.
You would also need a counter at the bottom of your script to add in the number.
$_SESSION['counter']++;
Using hidden inputs to replace sessions without array or for loop.
<?php
$counter = $counter + (int) $_POST['counter']; // (int) helps sanitise this by forcing type change to integer - any text would be converted to 0
//echo $counter; // for trackng
$texts = $_POST['texts']; // MUST be sanitized and escaped for mysqli
if($counter > 0) $texts = $texts . "<br />Question " . $counter . ": Something " . $_POST['question'];
$counter++;
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<textarea id="question" name="question"></textarea>
<input type="hidden" name="texts" id="texts" value="<?php echo $texts;?>" />
<input type="hidden" name="counter" id="counter" value="<?php echo $counter; ?>" />
<input type="submit"/>
</form>
<?php echo $texts; // put this in a div where you want to see them ?>
Do not use this code without cleaning up the post variables or you will get hacked to bits by hackers. See other posts on preg_replace() and on php.net
You can use hidden inputs if you keep echoing out the id values and the just submitted value. (Also, note how I added a name to the submit)
<form action="index.php" method="post">
<?php
if(isset ($_POST['submit']) {
$oldAnswers = array ();
if(isset($_POST['oldAnswers']) && is_array ( $_POST['oldAnswers'])) {
$oldAnswers = $_POST ['oldAnswers'];
}
if (isset ($_POST ['question']))
$oldAnswers[] = $_POST ['question'];
for($i = 0, $j = 1; $i < count (oldAnswers); $i++, $j++) {
$answer = $oldAnswers [$i];
// display your "previously written" message
echo 'Question ' . $j . ': ' . $answer . "<br>\n";
// echo out hidden inputs
echo '<input name="oldAnswers[]" type="hidden" value="' . $answer . '">';
}
}
?>
<textarea id="question" name="question">< /textarea>
<input name="submit" type="submit">
</form>
See how oldAnswers has [] after it in the name? That'll tell php that it's an array and make it easy to deal with.
