instead of echoing the error when it happens, set it as a variable then wherever you want the error to display, echo the variable

change this:

echo "Error: News title is a required field. Please fill it.";to this:

$error_news_title = "Error: News title is a required field. Please fill it.";im not sure what you mean about displaying "against" text boxes.

wherever you want the code to be displayed, just put this:

echo $error_news_title;and when you place your

<meta http-equiv=Refresh content=4;url=ALN.php>it needs to be in the <head></head> section.

you have this:

<html> <title>hotnews</title>

<body background=new2.jpg>but it should be this:

<html><head><title>hotnews</title>
<meta http-equiv=Refresh content=4;url=ALN.php>
</head>
<body background=new2.jpg>so if you want to choose whether to add the redirect or not (i would not use it either by the way... its not really the right application for it here)
you might do something like this:

echo "<html><head><title>hotnews</title>";
if (isset($_POST['submit']) && (!$title || !$text1 || !$text2)){
echo "<meta http-equiv=Refresh content=4;url=ALN.php>";
}
echo "</head><body background=new2.jpg>";i keep seeing things that dont look right to me. actually i would rewrite what you have a lot more.

Explain where you would like the error message. In the text area? under? over?
i can understand you not wanting the title to have digits but you also seemed to copy the same for text1 and text2 is that correct?

answer those and ill show you how i think it should be.

i want to display error message under or over the text box. and i also not wanting the title,text1 and text2 to have digits. it any one put digits then it should display an error.

in short i just want two things. any one leave any text box blank then it should display error under or over the text box.

second i want that if any one enter digits in any text box(title,text1 or text2) then it should display an error that digits are not allowed or what ever. just thats my conditions.

<?php

include("C:\\Program Files\\VertrigoServ\\www\\portal\\password_protect .php");
include("config.php");

//--------------------------------------------------------------------------------------------------------------------------

if(isset($_POST['submit'])) {

$title = mysql_escape_string($_POST['title']);
$text1 = mysql_escape_string($_POST['text1']);
$text2 = mysql_escape_string($_POST['text2']);

$error="no";
if (!$title) {
$title_error = "Error: News title is a required field. Please fill it.<br>";
$error="yes";
}
if (!$text1) {
$text1_error = "Error: News text1 is a required field. Please fill it.<br>";
$error="yes";
}
if (!$text2) {
$text2_error = "Error: News text2 is a required field. Please fill it.<br>";
$error="yes";
}

$num_error .= "Error: News must not contain numbers, text only.<br>&nbsp;&nbsp;Please refill it with all numbers removed.<br>";
if ((bool) preg_match('/[0-9]/', $title)) {
$title_error .= $num_error;
$error="yes";
}
if ((bool) preg_match('/[0-9]/', $text1)) {
$text1_error .= $num_error;
$error="yes";
}
if ((bool) preg_match('/[0-9]/', $text2)) {
$text2_error .= $num_error;
$error="yes";
}

$meta = "";
//run the query which adds the data gathered from the form into the database
if ($error=="no"){
$result = mysql_query("INSERT INTO news (title, dtime, text1, text2) VALUES ('$title',NOW(),'$text1','$text2')",$connect);

//print success message.
$success = "<br>Thank you! News added Successfully!<br>You'll be redirected to Home Page after (4) Seconds";
$meta = "<meta http-equiv=Refresh content=4;url=ALN.php>";
}
}

//--------------------------------------------------------------------------------------------------------------------------

$main = "<br><h3>::Add News</h3><br>";
$main .= "<form method='POST' action=''>";
$main .= "{$title_error}Title: <input name='title' size='40' maxlength='255'><br>";
