Newbie here with weird error.
Before I start - I've read and understood (at least I think so) this topic:
How to fix "Headers already sent" error in PHP
which has great overview of this error, but I did not find solution there.
Now the problem:
I have 2 simple .php files (05.php and 10.php)... both of them contain 5 table rows. First 3 columns are not relevant (simple text). Fourth column reads content of .txt file and displays it. Fifth column has 2 submit buttons("+" and "-") which basicly open .txt file, read number in it, changes it's value, replace value in file with changed one and refreshes site. I need to include both of those files in my "main.php" file.
When I open them separetly, they work fine, when I include any of them in "main.php", everything works fine, but when I include both of them, input buttons on firt 7 rows work fine, but buttons on rows 8-10 give me this error:
Warning: Cannot modify header information - headers already sent by
(output started at C:\xampp\htdocs\test\10.php:94) in
C:\xampp\htdocs\test\10.php on line 120
Second line number changes when I press different input buttons (which is obvious). First line number is always the same, and points to line with this code :
</form>
I cannot figure out what's wrong...
I know that this code is not "nice" and best way of doing this kind of stuff, but like I said... newbie on deck :)
Here are full codes of "05.php", "10.php" and "main.php"...
"05.php"

Any help is a great help :)
EDIT:
Instead of including those files, I've just copy/pasted their code into "main.php" and it is exactly the same. Separatly pasted works fine, pasted together give the same error...
Long story short
There must not be sent anything even a white space till all headers are sent.
The issue
In your case the script sends plenty of html code, text, etc. and then suddenly it tries to modify the headers with calls like header("Refresh:0"); and this is wrong.
You should send all the headers before the page content is sent to the browser.
Solution:
1. sent all headers at the beginning of the script and then continue with the content
OR
2. use Output Buffering to catch all the output and flush it after all modification of headers are done.
BUT do not mix output and headers together.
Proof of concept
You can comment all the lines with header("Refresh:0"); This should suppress the headers already sent php errors ;)
So im kinda trying to delete row from my mysql database using checkboxes. Here is my code. Would be glad if someone could write me down simple delete code. Tryed many but failed, stuck for hours with this :(

Welcome to StackOverflow! Generally as a rule of thumb asking to write you some code doesn't get you very far, however I know that some people learn better from seeing it implemented and being able to modify off of that.
There is a number of ways you can do this. Using something like jquery and ajax you can post your requests without having to reload the page. Keep in mind what I have below may not fully work for you since taking the time to do this much already without a database or connection should give you an idea of what you're looking to do. Good luck!
CAUTION: PSUEDO CODE (This may not fully work and is not intended for production) The idea is to show you an approach to achieving what you are looking for.

I cleaned up a bit of the html and styles, just made it easier for me to read. Also I would recommend looking into a library such as PDO to handle your database queries as there currently isn't much in place to protect or safe guard against sql injection.

Reference - What does this error mean in PHP?
(38 answers)
Closed 8 years ago.
I have to make one system where the system requires the process of adding new information. The process flow is the process of adding the new information carried by the employee where all the information, name and id of staff will insert in mysql database. When I tried the process of that, I found staff_id and staff_name was empty in database mysql.
This is my addStaff.php
<?php
include("authenticationStaff.php");
include ("dbase.php");
$query= "SELECT * FROM staff WHERE staff_name ='".$_SESSION['SESS_STAFF_NAME']."'";
$result = mysql_query($query);
$row = mysql_fetch_array($result);
$id = $row["id"];
$staff_id=$row["staff_id"];
#mysql_free_result($result);
?>
<html>
<head>
<script>
function Validate()
{
if (document.addStaff.project_name.value == '')
{
alert('Please Insert Project Name!');
document.addStaff.project_name.focus();
return false;
}
if (document.addStaff.project_id.value == '')
{
alert('Please Insert Project ID !');
document.addStaff.project_id.focus();
return false;
}
if (document.addStaff.location.value == '')
{
alert('Please Insert Location!');
document.addStaff.location.focus();
return false;
}
if (document.addStaff.cost.value == '')
{
alert('Please Insert Cost!');
document.addStaff.cost.focus();
return false;
}
if (document.addStaff.pic.value == '')
{

document.addStaff..pic.focus();

Can someone see where I am going wrong?if you need any more info then please let me know. thanks.
You need to use session_start(); at the start of every page that accesses the session values.
I am stuck with a problem.
I have HTML element inside PHP variable. Now i want if condition inside html elements.
My code is like this.
<?php
$x = 1;
$html =
'<style>
b
{
paading:0;
margin:0;
}
</style>
<table width="790px" style="font-family:Open Sans;">
<!--Want If Condition Here-->
if($x != 1)
{
<tr>
<td colspan="2">
My Separate Portion
</td>
</tr>
}
<strong></strong>
<tr> <td colspan="2"> <hr style="background-color:#E44510; height:10px;"> </td> </tr>';
echo $html;
?>
If anyone can help me out, its very appericiable.
<?php
$x = 1;
$html =
'<style>
b
{
paading:0;
margin:0;
}
</style>
<table width="790px" style="font-family:Open Sans;">';
if($x != 1)
{
$html .= '<tr>

</td>
</tr>';
}
$html .= '<strong></strong>
<tr> <td colspan="2"> <hr style="background-color:#E44510; height:10px;"> </td> </tr>';

The code
<a href="javascript:void(0)"
onClick="showpic('<?php echo $row[pic_path];?>','<?php echo $row[pic_id];?>',
'<?php echo $row[album_id];?>','<?php echo $row[pic_caption];?>')";>
<img src="<?php echo $row[pic_path];?>"/></a>
pass the album_id, pic_id to the javascript functions which is then passed to the objects in the lightbox such as id="t_albumid", id="t_imageid"
I need to write a SQL query in the lightbox like this:
SELECT * FROM candidate_pics_comment WHERE pic_id='$VariableHavingPicId
but for this I must use the variable in the JavaScript image_id and pass it again to the lightbox div in the JavaScript. The code:
document.getElementById('t_imageid').value = image_id;
assigns the object, the value as image_id, but how can we assign the image_id to a php variable so that I can use it in the sql query?
I mean in the JavaScript can it be something like this:
function showpic(image_path,image_id,album_id,pic_caption)
{
<?php
$var = //assign the value image_id;?>
// rest of the code here;
}
I know it's not possible, but is there some trick to achieve this?
Moreover as I was experimenting, I did something like this:
function showpic(image_path,image_id,album_id,pic_caption)
{
<?php
$_SESSION[pic_id]="hmmm";?>
//rest codes;
}
Then when I used echo $_SESSION[pic_id] in php script, it displayed hmmm
So I was thinking can it be done something like this?
function showpic(image_path,image_id,album_id,pic_caption)
{
<?php
$_SESSION[pic_id]=//assign image_id to session variable;?>
//rest codes;
}
Besides I used AJAX application, but I saw that AJAX returns the response to the objects innerHTML, how ca it be stored in a php variable?
Update
My question is that, I am passing values from this
<a href="javascript:void(0)"
onClick="showpic('<?php echo $row[pic_path];?>','<?php echo $row[pic_id];?>',
'<?php echo $row[album_id];?>','<?php echo $row[pic_caption];?>')";>
<img src="<?php echo $row[pic_path];?>"/></a>
to the JavaScript fiunction
function showpic(image_path,image_id,album_id,pic_caption)
Now how can I assign image_id to a PHP variable which I can use in the div AlbumDiv which is used for the lightbox. If that not possible how can a session variable be assign the value of image_id, is it possible inside the JavaScript function?
ajax is the only option to get something from JavaScript to PHP.
If you are using jQuery then take a look at the docs here
Otherwise I recommend you use a Library like jQuery or jQuery itself
