How to set up a search that uses checkboxes?

Question

Hi

I'm a total newb at php and mysql but using Dreamweaver I've managed to create a php webpage containing a series of checkboxes (I think of them as tags) and a text field (for URLs) that allows me to enter data into a database. I've done a test post, and it works.

The problem is, I don't know how to create a search function that will allow me to tick the same boxes and do a search that will bring up the URLs in the text field.

Can someone suggest how to edit my page to add a search option that brings up the results a user defines, with options to choose between showing the result that meet ALL defined criteria, or just SOME criteria? The results should open in a new page.

How the search should work - E.g. if we have links on the database that have the following tags:

AB
A
AC
B
C
BC

and a user ticks the boxes marked A & C, and also the button marked 'Show results that meet ANY criteria'. He would then see the following results:

AB
A
C
BC

However, if he had clicked 'Show results that meet ALL criteria' he would have gotten this instead:

AC

At this moment, I THINK I only need simple script that I could build on, so if someone can suggest a basic script to my homepage, I would be grateful.

I'll include my homepage script and also my database script, in case that helps. Thanks for reading this.

PHP allows you to use Array notation in your form field names.

eg:

<input type="checkbox" name="checked[check1]" />
<input type="checkbox" name="checked[check2]" />

When received in PHP, you get an Array.

eg:

$checked = $_GET['checked'];

If both the fields were checked, then $checked would be:

$checked; // array('check1'=>1, 'check2'=>1);

The array should easier to use, since it is indexed. Being indexed allows you to iterate through the Array, and thus group your code into a loop instead of having to write out each variable name in a linear (hard-coded) fashion.

eg:

GetSQLValueString(isset($_POST['apple']) ? "true" : "", "defined","'Y'","'N'"),
                       GetSQLValueString(isset($_POST['strawberry']) ? "true" : "", 

"defined","'Y'","'N'"),
                       GetSQLValueString(isset($_POST['liverpool']) ? "true" : "",

and the following 20 or so lines would be written as:

foreach($checked as $name=>$value) {
  // build the sql query here
}

Or even just a single implode() if possible.

This would allow you to create your search Query dynamically.

As for the search query itself:

it would look something like:

SELECT * FROM tablename where column1 = 'yes' AND column2 = 'no' ... etc.

If you break this down into pieces you can construct in a loop you get:

SELECT * FROM tablename // doesn't change
column1 = 'yes' // condition is dynamic
AND // connects each condition (boolean AND or OR)

so PHP would look like:

For the static part:

$sql = "SELECT * FROM tablename";

dynamic conditions

$conditions = array(); 
foreach($checked as $name=>$value) {
  $conditions[] = $name." = '".$value."'";
}

then you put the conditions together with AND or OR based on whether you want to match all or any.

$match_type = $_GET['match'] == 'all' ? ' AND ' : ' OR ';
$sql .= implode($match_type, $conditions);

This is just a basic template you could use.
