i have done as shown in this pic but its not working for me
Please tell me what you mean by ānot working for meā. What happens?
What happens if you open the page as I suggested above?
Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in C:\wamp64\www\site\admin\post.php on line 38

And what value are you putting in the address for āidā?
ābooleanā in this location tells you the attempt to run the query returned āfalseā instead of a results object.
i got that error when i put this as you said ?id=1

@srsingh83, if you include a hash mark ( # ) in your post you need to escape it for it to show up, that means, typing a backslash \ before the hash - ie you need to type \#
[/off-topic]
where to write it - #
Typo in this line?
"select * from comments where vid='$id' And Status='approved' order by id DESEC";
? what to do here thing this will come up when the above error get solved:)
Iām not sure what you mean. I think thereās a typing error in your query which is stopping it from running. When it doesnāt run, it returns āfalseā, which you should check for before your code continues. As you donāt, you then try to count the number of rows returned by the query, but instead of a results object you are passing in āfalseā to the function. So you get the error message you posted.
thatās why i asked for the help as i am not able to get whats wrong in the code
also i posted the pic from where i am writing the code it works but mine not
Wherever you have a # in your post.
Thatās fine, but forum help is generally to point you in the right direction rather than to just do the fixes for you. I think Iāve found the line of code thatās causing the problem (though Iām not 100% certain) - can you compare it to the line in the code that you downloaded? You didnāt show that line in your screen-shots in post #21 so Iām not sure itās the same.
yes i know forum is here to help thats why i am asking the help that whats gone wrong in the code
i have applied the code formatting and this is the updated and full code - post #21 is not there it was blank to applied the formatting and you can see now the things clearly
<?php

$row2 = mysqli_fetch_assoc( $sql2 );

the pic are from video so cannot post the code from it
Where is this being set?
I believe (though I may be wrong) that the problem lies in the query in this line of code:
$query4="select * from comments where vid='$id' And Status='approved' order by id DESEC";
which causes it not to run. Could you go through the query keyword by keyword, and see where there might be something spelled incorrectly?
When you then try to execute the query in this line
$sql = mysqli_query( $con, $query4 );
it returns false into $sql, because the query has a syntax error. So then when you run this line
if ( mysqli_num_rows( $sql ) > 0 ) {
you get the error message you gave us in post #23,
Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in C:\wamp64\www\site\admin\post.php on line 38
because youāre passing in $sql as parameter 1, which is now false, a Boolean value.
So, have a careful look through each keyword in that query, until you see which one is wrong.
When itās called from the browser line, I think - that must be OK, because itās not mentioning the undefined variable any more.

this is the last points my current problem is not solved yet
<?php
if ( isset( $_REQUEST[ 'id' ] ) ) {
$id = $_REQUEST[ 'id' ];
}
$query2 = "select * from video where vid='$id'";
$sql2 = mysqli_query( $con, $query2 );
$row2 = mysqli_fetch_assoc( $sql2 );

<h1>
<?php echo $row2['title'];?>
</h1>
<p>
<?php echo $row2['description'];?>
</p>
and i think if this solved the others can also be solved as the id is causing the issue
the further section is for the comment section which has to come after the video got display any my video is not coming so how to solve further thing first 
Hang on, the last error message you asked for help with was the fault with the second query, where you are passing false into it. What is your ācurrent problemā?
i showed up the full code for the page but first showed the id error which not solved and then i showed you that what i am trying to do
first to display video with title and description and then comment thing
