Hello,

I was thinking a way to search more then 3 fields using LIKE my sql query i tried this way but its getting all the products not for the one it searched for

if(isset($_POST['search_now'])){ 
          if(isset($_GET['go'])){ 
              if(preg_match("/^[  a-zA-Z0-9]+/", $_POST['brand'] || $_POST['model'] || $_POST['new'])) { 
                  $new   = $_POST['new'];;
                  $brand = $_POST['brand']; 
                  $model = $_POST['model']; 
                  $mtrl  = $_POST['material'];
    $query1 = "SELECT * FROM products WHERE brand LIKE '%$brand%' OR model LIKE '%$model%' OR mtrl LIKE '%$papers%' ";
    $prod_set  = mysqli_query($connection, $query1);

    @hericles is right, that is what happens. The variable `$paper` never gets a value. Your `if` on line 3 is probably not what you want. My guess is you want this: if ( preg_match("/^[ a-zA-Z0-9]+/", $_POST['brand']) && preg_match("/^[ a-zA-Z0-9]+/", $_POST['model']) && preg_match("/^[ a-zA-Z0-9]+/", $_POST['new']) ) Meaning all three search terms … Read More

Are each of your search values (brand, model and paper) actual values?
If they are empty values then they will return everything as
LIKE '%$brand%' is equivalent to LIKE '%%' if $brand is an empty value, which matches all values in that column.

if (
    preg_match("/^[ a-zA-Z0-9]+/", $_POST['brand']) &&

    preg_match("/^[ a-zA-Z0-9]+/", $_POST['new'])
)

Meaning all three search terms need to have a value.

still facing the same when i search 1 query it gives me all prodcuts stored in the database not only the one which i search for

this is the modified code

 if(isset($_POST['search_now'])){ 
          if(isset($_GET['go'])){ 
              if(preg_match("/^[  a-zA-Z0-9]+/", $_POST['brand']) &&
                 preg_match("/^[  a-zA-Z0-9]+/", $_POST['model']) &&
                 preg_match("/^[  a-zA-Z0-9]+/", $_POST['material'])) { 
                  $new   = $_POST['new'];
                  $used  = $_POST['used'];
                  $year  = $_POST['year']; 
                  $box   = $_POST['box'];
                  $papers= $_POST['papers'];
                  $brand = $_POST['brand']; 
                  $model = $_POST['model']; 
                  $mtrl  = $_POST['material'];
    $query1 = "SELECT * FROM products WHERE brand LIKE '%$brand%' OR model LIKE '%$model%' OR mtrl LIKE '%$papers%' ";
    $prod_set  = mysqli_query($connection, $query1);

Still the same issue. If the three fields are filled (which you check), but papers isnt, you'll get mtrl LIKE %% which selects all records.

if(preg_match("/^[  a-zA-Z0-9]+/", $_POST['brand']) &&
                 preg_match("/^[  a-zA-Z0-9]+/", $_POST['model']) &&
                 preg_match("/^[  a-zA-Z0-9]+/", $_POST['material'])) { 
                  $brand = $_POST['brand']; 
                  $model = $_POST['model']; 
                  $mtrl  = $_POST['material'];
    $query1 = "SELECT * FROM products WHERE brand LIKE '%$brand%' AND model LIKE '%$model%' AND mtrl LIKE '%$mtrl%' ";

here is my updated code. like if 3 fieds are filled then its finding correctly but if like someone only go for brand and rest he feels to be empty so can show or filter brand only does it make sense though??

so if i want to add more 2 to 3 fields so in that view

Make those parameters optional, so only add the WHERE clause for a column, if that valkue actually has a value. Like this:

$query1 = " SELECT * FROM products WHERE 1=1 ";

$brand = $_POST['brand'];
if (!empty($brand) && preg_match("/^[ a-zA-Z0-9]+/", $brand))
{
    $query1 .= " AND brand LIKE '%$brand%' ";
}

//repeat

Here is the form to make you thing confirm what i am looking for let me try your given query as well but didn't understood WHERE 1=1
