first textfield should be disabled and when i clicked on check box, textfield should be active.
echo'<input type="checkbox" name="checkbox"/>';
echo'<textarea name="explain" id="explain"
cols="" rows="" style="width:300 ;height:300"></textarea>
if(isset($_POST['checkbox']))
{
???
}
I think you should use this:
<form>
<input type="checkbox" name="checkbox" onchange="toggleDisabled(this.checked)"/>
<textarea name="explain" id="explain"></textarea>
</form>
<script>
function toggleDisabled(checked) {
document.getElementById('explain').disabled = checked ? false : true;
}
</script>
Full code is here
Your question a little unclear. I've interpreted this as you needing JavaScript to set the textarea to disabled and active on a checkbox value without going to the server.
Using Javascript you can add an event listener on the checkbox and check the checked property, then set the textarea to disabled or not.
document.getElementById("checkbox").addEventListener("click", checkbox_textarea);
function checkbox_textarea() {
if( this.checked == true ) {
document.getElementById("textarea").disabled = false;
return false;
}
document.getElementById("textarea").disabled = true;
}
<input id=checkbox type=checkbox name=chk /> Enable text area <br />
<textarea id=textarea name=txt cols=50 rows=20 disabled></textarea>

Hello i want to check if the textarea isnt empty and i still can´t get the echo that i want even when the textarea isnt empty and input is set
here is my code:
<form method="post" action="">
<input type="text" name="jmeno"/>
<textarea name="textarea" id="textarea" rows="5" cols="40"></textarea>
<input type="submit" name="submit"/>
</form>
<?php
if(isset($_POST['jmeno']) AND !empty($_POST['textarea'])){
echo "dokončeno";
}
?>
How about this:
if (!is_null($_POST['jmeno']) && strlen(trim($_POST['jmeno'])) > 0) {
echo "dokončeno";
}
As far as I understand you want your code to check if the submit button is pressed and the textarea isn't empty. I would say the code is:
if(isset($_POST['jmeno'])){
if(strlen($_POST['textarea']) > 0){
echo "dokončeno";
}
}
OR simply:
if(isset($_POST['jmeno']) && strlen($_POST['textarea']) > 0){
echo "dokončeno";
}
if (isset($_POST['jmeno']) && strlen(trim($_POST['textarea']))>0)
{
echo "dokončeno";
}

form.html
<form name="input" action="process.php" method="post">
<input type="text" name="user" placeholder="Enter Your Name">
<input type="text" name="message" placeholder="Enter A Message">
<br>
<input class="shout-btn" type="submit" name="submit" value="Shout It Out">
</form>
process.php
<?php
include "database.php";
echo var_dump($_POST);
if(isset($_POST['submit'])){
$user = mysqli_real_escape_string($con,$_POST['user']);
$message = mysqli_real_escape_string($con,$_POST['message']);
//SET TIMEZONE
date_default_timezone_set('America/New_York');
$time = date('h:i:s a',time());
if (!isset($user) || $user == "" || !isset($message) || $message == "") {
echo "bad";
} else {
echo "good";
}
}
?>
For some reason $_POST gives me text variable:
array(3) { ["text"]=> string(5) "david" ["message"]=> string(27) "adasdasdasdasdasd asdasdasd" ["submit"]=> string(12) "Shout It Out" }
Notice: Undefined index: user in D:\xampp\htdocs\php\shoutit\process.php on line 6
bad
Either you've retyped form.html correctly on SO and there is an error in you actual code (mainly calling the name field text), or you had it like this, then fixed it and the your browser is caching the old version.
Easy way to check, in your browser view source on the form and check the form name.
Clear your cache and try again.

i have an if statement as follows
if($_POST['remember']=="on")
i want to know if this is the correct syntax for checking if the checkbox is checked or unchecked?
This code will help you
<input type="checkbox" name="checkbx" <?php if(isset($_POST['remember'])=="on") echo "checked";?> />
OR
<?php if(isset($_POST['remember'])=="on") {?>
<input type="checkbox" name="checkbx" checked="checked" />
<?php }else {?>
<input type="checkbox" name="checkbx" />
<?php }?>
simple check of isset
if(isset($_POST['remember']) && $_POST['remember']=="on")
{
// checkbox remember is checked
}
else
{
// checkbox remember is not checked
}
Use
if (isset($_POST['remember'])) {
// checked
} else {
not checked
}
<input type="checkbox" name="remember" value="YES" />
$remember= ($_POST['remember'] == 'YES')?'YES':'NO';
