Multiple checkbox search

[only1perky]

Hi guys could someone please help me out before I go insane.

I'm completely new to php so you'll have to be patient with my stupidity.

 

My database contains a table with about 50 categories that are all either true or false (obviously marked as 1 or 0).

 

I would like to search this table based on which checkboxes are ticked and return the results accordingly.

 

I know I need to include a foreach in my query but I just can't get my head round what I need to do.

Could someone please just write my query for me so I can move on and get confused with something else.

 

Here is my form (I've only put 3 checkboxes to keep it short)

Form:

<form name="advancedsearch" action="search.php" method="post" >
<input name="criteria[]" type="checkbox" value="realale" />
<input name="criteria[]" type="checkbox" value="fruitwine" />
<input name="criteria[]" type="checkbox" value="champagne" />
<input type="submit" name="submit" value="Submit">
</form>

 

I also have this script which I've been using to search from a text box. Is it possible to use this code with the checkboxes? (Obviously a few alteration will be needed.

 

 

<?php
if(isset($_GET['search-d'])){
  // Get the search variable from URL

  $var = @$_GET['search-d'] ;
  $trimmed = trim($var); //trim whitespace from the stored variable

// rows to return
$limit=10; 

// check for an empty string and display a message.
if ($trimmed == "")
  {
  echo "<p>You failed to enter a search parameter...</p>"; ?>
   <a href="javascript:history.go(-1)">Click here to search again</a>
<?php  }else {

// check for a search parameter
if (!isset($var))
  {
  echo "<p>We dont seem to have a search parameter!</p>";
  exit;
  }


// Build SQL Query  
mysql_select_db($database_connuser, $connuser) or die;
$query = "select * from drinking  WHERE " .$trimmed. " = 1 order by venue asc"; // EDIT HERE and specify your table and field names for the SQL query

$numresults=mysql_query($query);
$numrows=mysql_num_rows($numresults);

// If we have no results, offer a google search as an alternative

if ($numrows == 0)
  {
  echo "<h4>Results</h4>";
  echo "<p>Sorry, your search for pubs serving "" . $trimmed . "" returned zero results</p>";
?><?php
// google
echo "<p><a href=\"http://www.google.com/search?q=" 
  . $trimmed . "\" target=\"_blank\" title=\"Look up 
  " . $trimmed . " on Google\">Click here</a> to try the 
  search on google</p>";
  }else{

// next determine if s has been passed to script, if not use 0
  if (empty($s)) {
  $s=0;
  }

// get results
  $query .= " limit $s,$limit";
  $result = mysql_query($query) or die("Couldn't execute query");

// display what the person searched for
echo "<p>You searched for pubs serving "" . $var . ""</p>";

// begin to show results set
echo "";?><br/><?
$count = 1 + $s ;


// now you can display the results returned
  
?>
<table width="100%" border="0" class="tabletext">
  <tr>
    <td width="13"></td>
    <td width="60"></td>
    <td width="92"></td>
    <td width="127"></td>
    <td width="79"></td>
  </tr>
  
  <tr>
    <td colspan="4"><p><strong>Venue Name</strong></p></td>
    <td> </td>
  </tr>
  <?php while ($row= mysql_fetch_array($result)) { ?>
  <tr>
    <td colspan="4" bgcolor="#FFFFFF"> </td>
    <td bgcolor="#FFFFFF"> </td>
  </tr>
  <tr>
    <td colspan="4" bgcolor="#FFFFFF"><p><STRONG><?php echo $row['venue'];
?></STRONG><br>
      <strong>Address:</strong> <?php echo $row['address'];?>, <?php echo $row['area'];?></p></td>
    <td bgcolor="#FFFFFF"><p class="subhead"><a href="venuedetails.php?id=<?php echo $row['id']; ?>">More Info</a><br>
      <a href="http://www.multimap.com/maps/?qs=<?php echo $row['postcode']?>&countryCode=GB">View Map</a></p></td>
  <?php
$count++ ;
  

} ?>
</tr>
</table>
<?php 
$currPage = (($s/$limit) + 1);
//break before paging
  echo "<br />";

  // next we need to do the links to other results
  if ($s>=1) { // bypass PREV link if s is 0
  $prevs=($s-$limit);
  print " <a href=\"$PHP_SELF?s=$prevs&search-q=$var\"><< 
  Prev 10</a>&nbsp ";
  }

// calculate number of pages needing links
  $pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division

  if ($numrows%$limit) {
  // has remainder so add one page
  $pages++;
  }

// check to see if last page
  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

  // not last page so give NEXT link
  $news=$s+$limit;

  echo " <a href=\"$PHP_SELF?s=$news&search-q=$var\">Next 10 >></a>";
  }

$a = $s + ($limit) ;
  if ($a > $numrows) { $a = $numrows ; }
  $b = $s + 1 ;
  echo "<p>Showing results $b to $a of $numrows</p>";
  
  }}}
?>

 

Hope you can help. Thanks.

i think you want this

$find = implode("=1 AND ",$_POST['criteria'])."=1";
$query = "select * from drinking  WHERE $find order by venue asc";
//RESULT = $query= "select * from drinking WHERE realale=1 AND fruitwine=1 AND champagne=1 order by venue asc";
