PHP MYSQL search with checkboxes

[compgeek83]

having a small issue setting up a search, trying to use check boxes, here is my form code

 

<form action="workorder_index.php" method="POST">
<input type="checkbox" name="wos_0" <? if($wos_0 != NULL) { echo "checked"; }?>>0 - Active
<input type="checkbox" name="wos_1" <? if($wos_1 != NULL) { echo "checked"; }?>>1 - Completed awaiting pickup
<input type="checkbox" name="wos_2" <? if($wos_2 != NULL) { echo "checked"; }?>>2 - Completed and out the door
<input type="checkbox" name="wos_3" <? if($wos_3 != NULL) { echo "checked"; }?>>3 - Waiting call back
<input type="checkbox" name="wos_4" <? if($wos_4 != NULL) { echo "checked"; }?>>4 - Waiting for parts<br>
<input type="checkbox" name="wos_5" <? if($wos_5 != NULL) { echo "checked"; }?>>5 - Parts in waiting for completion
<input type="checkbox" name="wos_6" <? if($wos_6 != NULL) { echo "checked"; }?>>6 - not used
<input type="checkbox" name="wos_7" <? if($wos_7 != NULL) { echo "checked"; }?>>7 - Overdue for pickup
<input type="checkbox" name="wos_8" <? if($wos_8 != NULL) { echo "checked"; }?>>8 - Scrapped per customer
<input type="checkbox" name="wos_9" <? if($wos_9 != NULL) { echo "checked"; }?>>9 - Scrapped by overdue<br><br>
<input type="hidden" value="1" name="customsearch">
<input type="Submit" value="Update">
</form>

 

here is my handling code

 

$wos_0=$_POST[wos_0];
$wos_1=$_POST[wos_1];
$wos_2=$_POST[wos_2];
$wos_3=$_POST[wos_3];
$wos_4=$_POST[wos_4];
$wos_5=$_POST[wos_5];
$wos_6=$_POST[wos_6];
$wos_7=$_POST[wos_7];
$wos_8=$_POST[wos_8];
$wos_9=$_POST[wos_9];

if(isset($_POST['customsearch'])) {
$str='';
if($wos_0 != NULL) {
	$str.= "'0'";
}
if($wos_1 != NULL) {
	$str.= ",'1'";
}
if($wos_2 != NULL) {
	$str.= ",'2'";
}
if($wos_3 != NULL) {
	$str.= ",'3'";
}
if($wos_4 != NULL) {
	$str.= ",'4'";
}
if($wos_5 != NULL) {
	$str.= ",'5'";
}
if($wos_6 != NULL) {
	$str.= ",'6'";
}
if($wos_7 != NULL) {
	$str.= ",'7'";
}
if($wos_8 != NULL) {
	$str.= ",'8'";
}
if($wos_9 != NULL) {
	$str.= ",'9'";
}

$query="SELECT * FROM workorders a INNER JOIN customers b ON a.customer_id = b.customer_id WHERE a.workorder_status IN (".$str.") ORDER BY a.workorder_id";

}

 

everything works as intended as long as the first check box remains checked, the others can be checked or not, if the first box gets unchecked I get this error

 

SELECT * FROM workorders a INNER JOIN customers b ON a.customer_id = b.customer_id WHERE a.workorder_status IN (,'1','2','3','4','5','6','7','8','9') ORDER BY a.workorder_id

Warning: mysql_numrows() expects parameter 1 to be resource, boolean given in workorder_index.php on line 84

 

basically I can't get the commas right, ...? any help is much appreciated

Put this just before your query,

if($str[0]==',')
{
  $str =  substr($str,1);
}

$query="SELECT * FROM workorders a INNER JOIN customers b ON a.customer_id = b.customer_id WHERE a.workorder_status IN (".$str.") ORDER BY a.workorder_id";
