How to check textarea value is submitted or not on insert page?

if (isset($share)){
//do stuff
}

or anything else?

I'm using click function #share instead form submit.
How to check #share is clicked, on insert.php page?
config.php

$host="localhost";
$user="";
$password="";
$db="";

$link = mysql_connect("$host", "$user", "$password");
$con=mysql_select_db("$db")or die(mysql_error());

index.php

Add another parameter to the data: part in your jquery function. There is no other way to know if user has clicked on Share since this is not a form element.

var DATA = 'status=' + status + '&share=true';

try that:

if (isset($_POST['share'])){ 
//do stuff 
}

Aren't you in the middle of another thread with this issue?

I want to stop user go directly to following and insert empty records to database

http://localhost/code/insert.php

So I want to check submitted or not on insert.php before insert any record.

I think this small change might work for you:

if (isset($_POST['status'])){ 
//do stuff 
}

The textarea wouldn't be populated unless the submit button was entered ... probably not the ideal solution, but should work

I know what you're trying to do. The post var I showed you is the std way (imo). You must have a mistake elsewhere.

Also the .input change to #content and use .html() or text() can't remember which

your insert.php page:

<?php
include("config.php");
 
if(isset($_POST['status']){
	//field is set
	$status = $_POST["status"];
	$status = str_replace("'",'&#39;',$status);//take out single quotes so they dont mess up the sql
	if($status != ''){
		$query = "INSERT INTO streams (message) VALUES ('$status')";
		mysql_query($query) or die(mysql_error());
	}else{
		//$status was empty
	}
}else{
	//status was not set
}
?>

also like ardav said

var status=$(".input").val();

would be better being

var status=$("#content").val();

.input refers to the class which is usually assigned to many elements but #content is an id and only given to one element. val() is correct
