Hi frds..........
I want to search by "Age" and "Blood Group" first.On combobox when I select both Age and Blood Group it gives the rihgt result but when I select only one field and other remain blank it not works.............
I want when I select only one field, query executes for one condition only....
It means when I select only Blood Group and leave Age field blank it displays all Name have required Blood Group without any age condition.

Use the following...

Replace your select box like this..

echo "Select Blood Group &nbsp&nbsp<select name='BloodGroup'><option value='none'>Select</option>"; // This will user friendly, when displaying 'Select' text, rather leaving it as a blank...
while($row=mysqli_fetch_array($result)){echo "<option>".$row[BloodGroup]."</option>";}echo "</select><br>";

Now, Your query will be succeeded based on some conditions...

if(($Bloodgroup=='none')&&($Age==""))
{
echo "Sorry.. Please enter valid bloodgroup and Age..";
exit;
}
if(($Bloodgroup!='none') && ($Age==""))
{
$query="select * from registration WHERE  Flag='A' AND BloodGroup= '$BloodGroup';
// Then your code as usual to display all results...
}
if(($Bloodgroup=='none') && ($Age!=""))
{
$query="select * from registration WHERE  Flag='A' AND Age='$Age';
// Then your code as usual to display all results...
}

This will works as your wish... If still any probs, please let me know...

I have one more problem that I have 3 tables named "events","participation","registration"....
All above values are retrieved by registration table such as Activity, Age, Blood Group.
Events table has 2 columns "EventId" and "Title".
Participation table has 2 columns "LoginId" and "EventId".
Registraion table contains many columns such as Name,LoginId,Activity, Age, Blood Group etc.

Now I want when user select Events Titles (displayed from table events). If selected title exists in table participation (by joining EventId condition) then it displays the corresponding Name which exist in registration table.


How I can do it...........
Plzzzz help me.........
Thx in advance..............
