With this part of query you could to have a problems…

WHERE CONCAT('id','firstname','mobilenumber','email','age','gender','gender','bloodgroup','location','posting_date' ) LIKE '%".$searchValue."%'"

And actually you get one “gender” more.

Better replace it with OR or UNION or at least CONCAT_WS().

I use an AJAX search very similar to the above and find the results van be incorrect because the fields are concatenated. The search term may be true and incorrect if part of the search term contains characters from the previous and next fields.

Your code only seems to execute the search query if the user doesn’t submit the form.

I also don’t like that method of concatenating fields to apply the search to any of them. Apart from anything else, it’s going to provide false positives as @John_Betong said.

Why don’t you use DataTables plugin with ajax server side processing?
