Help with message please: Warning: mysql_free_result() expects parameter 1 to be resource, null given in...... line

I would really appreciate some help with my search & results page that is now throwing up the following error:
Warning: mysql_free_result() expects parameter 1 to be resource, null given in...... line (the line number refers to the following code:

mysql_free_result($RSsearchforsale);

mysql_free_result($RsSearchForSale2);

mysql_free_result($RsSearchForSale3);

mysql_free_result($RsSearchForSale4);

I am new to php and am setting up a dynamic site in Dreamweaver (thanks to the Missing Manual – very helpful). I apologise in advanced for my lengthy description of the problem (perhaps get yourself a drink before continuing!)

I have a Search page with 4 list menus where the user can select an option from ANY or ALL of the menus, if a menu is not selected the value posted to the results page will be 'zzz'.

On the results page I have 4 recordsets, all getting the correct results, only one recordset is required to run depending on how many of the menus from the search page have been selected and a test is run before executing the sql using a SWITCH statement checking how many of the menus had passed the 'zzz' values from the Search page if you see what I mean. The results page has Repeating Regions, Recordset Paging and Display Record Count. The exact result that I require are generated by this method.

THE PROBLEM, when a user makes a selection the first page of 10 results is fine, but the error message above is shown at the bottom of the page, AND when the user clicks NEXT to go to the next page of results THERE ARE NO RESULTS.

This is exactly what happens depending on how many menus selected and which recordset is used:

4 menus selected from Search: runs RSsearchforsale, results correct but 3 error messages on 1st page relating to mysql_free_result($RsSearchForSale2),mysql_free_result($RsSearchForSale3), & mysql_free_result($RsSearchForSale4). The display record count shows correct results found. NEXT page is empty of results and still shows the correct display record count as if it should be displaying the records, also has the same 3 error messages.

3 menus selected from Search: runs RsSearchForSale2, results correct but 3 error messages on 1st page relating to mysql_free_result($RSsearchforsale),mysql_free_result($RsSearchForSale3), & mysql_free_result($RsSearchForSale4). The display record count shows correct number of results. NEXT page shows results from the DEFAULT setting of the recordset and the Display record count reflects this new set of results. Also still shows the 3 mysql_free_results for RsSearchForSale2, 3 and 4.

2 menus selected from Search: runs RsSearchForSale3, results correct but 2 error messages on 1st page relating to mysql_free_result($RSsearchforsale) & mysql_free_result (RsSearchForSale4). The display record count is correct. NEXT page does exactly the same as described in above 3 menus selected.

1 menu selected from search: runs RsSearchForSale4, results correct but 1 error meaasge on 1st page, mysql_free_result($RSsearchforsale). Display record count is correct and again when NEXT page is selected does as described in above where 2 or 3 menus selected.

If you have gotten this far without falling asleep then thank you and well done! I have pasted my code below and I know its a lot to ask but please please can you give me an idea as to where or why I have gone wrong. I felt I was so close at perfecting this search and have been working on it for weeks now. I feel sure the problem is because I have 4 recordsets on the page but I could find no other way to get the exact results I wanted from the menus.
Looking forward to any help.

I am marking this question as answered now as David has spent alot of time helping me and the origianl problem has been answered. I have been working on the fact that i cannot get results when only 3, 2, or 1 menu selected perhaps its my tables but all looks right. Anyway i´ll continue tonight and if still cannot work out i´ll re post under a seperate topic.

Change the following code:

mysql_free_result($RSsearchforsale);
mysql_free_result($RsSearchForSale2);
mysql_free_result($RsSearchForSale3);
mysql_free_result($RsSearchForSale4);

to this:

if (is_resource($RSsearchforsale)) mysql_free_result($RSsearchforsale);
if (is_resource($RsSearchForSale2)) mysql_free_result($RsSearchForSale2);
if (is_resource($RsSearchForSale3)) mysql_free_result($RsSearchForSale3);
if (is_resource($RsSearchForSale4)) mysql_free_result($RsSearchForSale4);

Hi David,

Thank you for that, i no longer get the errors (actually i had done and if else statement around the free-mysql to do if totalRows > 0 which also seemed to do the job but i´ve changed my code again to what you suggested as it bound to be better).

I do still have the problem with the NEXT page of results not getting results, please could you give me suggestions as to why this would be and ideas of how to correct it as the rest of this search works, as per my description i am only getting the 1st page of 10 results and the NEXT (2nd page) is either empty but showing correct recordcount (if 4 menus selected) or it shows the default results for the defaults entered into the dreamweaver recordset variable and the recordcount then reflects this new search (if 3, 2, 1 menu selected from.

Realy look forward to hearing from you.

If you're getting a parse error, the problem isn't on line 73, but somewhere before that. You have probably omitted a semicolon somewhere.

Hi David,

Thank you for getting back to me. I´ve corrected the error i was getting basically by starting over again so i had obviously done something wrong.

Now, i followed your tutorial, (code pasted below), the Next (2nd) page works fine now, BUT the search is just finding every record i have everytime where i wanted to find exact results using sql AND whether 1, 2, 3, or all 4 of the list meus were selected from the search. I´m obviously missing something but think i have changed everything as per instructions. How would i make it find exact results? The 4 fields Location, Type, Price & Beds are all column names in my main details table.

Look forward to hearing from you,

Tessimon
