[resolved] Count(*) my query?

Hi,

I’m having problems with my pagination search results page.  I’m getting the message:

[b]Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/***********/results.php on line 38[/b]

Which is part of this line:

[code=php:0]
    $query_count = mysql_query ( "SELECT COUNT(*) AS total FROM news_stories WHERE " . $search_query );
    $result_count = mysql_fetch_assoc ( $query_count );
[/code]

However, I can’t see what is wrong?  Is it not seeing my $search_query and paginating the results?

[code=php:0]  $search_query = "select *, DATE_FORMAT(appeared, '%W %d %M, %Y') as published_date from news_stories where section like '%$section%' AND unix_timestamp(published) <= unix_timestamp(NOW()) AND ( headline LIKE '%$searchstring%' OR story_text LIKE '%$searchstring%' ) Order by id Asc" or die(mysql_error()); [/code]

Can someone please help?

Thanks

Chris

There is maybe something is wrong with your query,
$query_count = mysql_query ( "SELECT COUNT(*) AS total FROM news_stories WHERE " . $search_query );
Normally after Where, there should be 1 or more condition. 

You should echo your query to see is it a valid query.  Do this before you execute the query.

Your query is wrong... If you look at what your query looks like, it's like this:

[color=blue]SELECT COUNT(*) AS total FROM news_stories WHERE select *, DATE_FORMAT(appeared, '%W %d %M, %Y') as published_date from news_stories where section like '%$section%' AND unix_timestamp(published) <= unix_timestamp(NOW()) AND ( headline LIKE '%$searchstring%' OR story_text LIKE '%$searchstring%'[/color]

This is not valid SQL.

Thanks Guys,

I've changed my query to:

[code=php:0]
$search_query = "select * from news_stories where section like '%$section%' AND unix_timestamp(published) <= unix_timestamp(NOW()) AND ( headline LIKE '%$searchstring%' OR story_text LIKE '%$searchstring%' ) Order by id Asc";
[/code]

Which is a valid query as i've tested it in phpmyadmin.  However i'm still getting the same error message:

[b]Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/***********/results.php on line 38[/b]

So why is my Count(*) line:

  [code=php:0] $query_count = mysql_query ( "SELECT COUNT(*) AS total FROM news_stories WHERE " . $search_query ); [/code]

Not Working with this line?

[code=php:0]$result_count = mysql_fetch_assoc ( $query_count ); [/code]

Many Thanks

Chris

It's still not valid... That query now looks like this:

SELECT COUNT(*) AS total FROM news_stories WHERE select * from news_stories where section like '%$section%' AND unix_timestamp(published) <= unix_timestamp(NOW()) AND ( headline LIKE '%$searchstring%' OR story_text LIKE '%$searchstring%' ) Order by id Asc

Try this...

[code]
<?php
$search_query = "SELECT * FROM news_stories WHERE section LIKE '%$section%' AND unix_timestamp(published) <= unix_timestamp(NOW()) AND ( headline LIKE '%$searchstring%' OR story_text LIKE '%$searchstring%' ) ORDER BY id";

$result = mysql_query($search_query);

$result_count = mysql_num_rows($result);
?>[/code]

Hi Huggie,

Thanks for your help.  From what i've read I would have thought i'm nearly there from this.  I've gone back and used a simple query to check it's all working

So With my pagination script I get:

- It to output all the results in the DB
- I get it so it displays pagination previous and next buttons

BUT IT DOES NOT LIMIT MY RESULTS - ie it displays all the results on one page:

[url=http://www.greenocktelegraph.co.uk/gtele/search_test/results_works.php]http://www.greenocktelegraph.co.uk/gtele/search_test/results_works.php[/url]

Now I know I have to do something with this line:

[code=php:0]$query_count = mysql_query ( "SELECT COUNT(*) AS total From news_stories" );  [/code]

To incorporate this query:

[code=php:0]    $search_query = "select * from news_stories"; [/code]

But I’m not sure what?

I just need it to count the results?

Thanks

Chris
