You're going to have to wait for someone else to help you. Twice I've asked you to show me the start of the file that is causing the error(connection.php) and I dont seem to be heard.

[greatstar00]

if that connection.php is that secret, u dont want to show it

we cant help u,

cause that error message line (at your 1st post), the message stating the connection.php is having error.

if u dont show that, we cant help u

 

if you dont show the file, then we cant help even it is your final second

only god can help u

 

 

here is what i suggest you to do before showing that connection.php

use **** to replace the mysql address, username, password, db name

[jl5501]

as people here are trying to tell you, your error message clearly states:

 

output started at C:\xampp\htdocs\widget_corp\includes\connection.php:1)

 

That means that something on line 1 of that file, is producing output. It may be as simple as a space before the <?php or may be something else, but that is where your error is.

[azeem123456]

oh i read it wrong sir i thought  u asking me content.php  sir i didnt make seperate db connection file

as i m new learner of php so i m not perfect in it there is nothing important for me sir.... all i want to learn and gain knowlegde sir could you tell me your email adress i send you my whole project and file to your email adress then u mite eaisly sort out my problem

ths is how i made my dataabase connection sir

<?php

$connection = mysql_connect("localhost","root","");

if (!$connection){

die ("Database connection failed".mysql_error());

}

$db_select= mysql_select_db("widget_corp",$connection);

 

if (!$db_select){

die ("Database selection failed".mysql_error());

}

?>

 

in html body 

there is my queries as u have seen above i provide you what you just asked me or give me email id  please

 

 

at the end i close my  conection ?php

mysql_close($connection);

?>

 

 

[jl5501]

ok, good, so as you can see, the first thing visible in that file, is the <?php 

 

You need to ensure there are no blank lines above that, or spaces in front of the <?php

 

The <?php must be right at the start of the file

[greatstar00]

by reading this code, we cant find the error

as u said, u can send the project to email

here is mine

[email protected]

this is only  my advertising email, meaning only receive ads, kinda of useless

so, u can send this time only

i wont check mails here ever after unless requested

[azeem123456]

so kindly check it out please

thanks

[greatstar00]

as i check your code, it doesnt got any problem

it redirects me to content.php

 

well, try to delete the extra line feed after the ?>  (the very end) of connection.php (i didnt delete this, and it worked)

 

 

i am running php 5.3

[azeem123456]
