Comparing string from array with mysql field

ttmtake · 11-27-2010, 11:03 AM

Hi, i have one problem with my search script

i have multiple checkboxes in search form, when user check eg. 5 boxes, after form process i take array and implode that array into one string and i get eg. $implodString = 1|4|27|34|55;

So, what i need is a way to compare this with mysql field where i have just one value eg. |4| - (this is in my field).

I need something like this
SELECT FROM `TABLE` WHERE `FIELD` LIKE %$implodString%

with showen values looks like this

SELECT FROM `TABLE` WHERE `|4|` LIKE % 1|4|27|34|55 %

i need to find all fields where we have any number from imploded array, in this case i need all fields where we have number 1,4,27,34 or 55.

Thank you for help.

I got something, this checks 2 rows,

PHP Code:


			
$checkDB = mysql_query("SELECT * FROM `table`");
while($row = mysql_fetch_array($checkDB)) { 

      
      $rowCat = str_replace('|','', $row['cat']);
      $rowCity = str_replace('|','', $row['city']);
     
      $cat = array($_POST['cat']); 
      $city= array($_POST['city']); 
      foreach($rowCat as $values){
      foreach($rowCity as $valuez){      
      
          if(in_array($cat, $values) && in_array($city, $valuez)) {
          echo $row['id'];
      }
                                }
                                   }
    }

Would the IN() function of MySQL be a better approach to the problem.

sql Code:

SELECT * FROM `table` WHERE `field` IN(1, 4, 27, 34, 55)

lol, tnx, i total forgot on IN(),

Firstly i was looked a way to compare two array srings eg. 2,4,6,9 compare with 5,3,2,4,7,8, but i cant find way to do that, so i add just one value in field and i just continue to write and forgot IN(), if u have any suggestion on how to compare 2 different array please write, (it will be a case when these 2 arrays wouldnt have same number of values inside, eg. 3,4,5 and 5,6,4,2 - in 1 array we have 3 values and in sec. we have 4.)
