unable to vaidate select field

[$php_mysql$]

hey guys im with no issue being able to validate the input field but select part i get error

 

my coding

 

$name=$_POST["name"]; 
$cat=$_POST["listing"];  //this is the select line
$state=$_POST["state"]; //this is the select line
$type=$_POST["type"]; 


if(empty($name) || empty($ad) || empty($location)) {
echo "<h3 align=\"center\">Error!</h3>\n";
echo "All fields are must<br/>";
die ("<h3 align=\"center\"><a href=\"index.php?action=main\">Home</a></h3>\n"); 
}

here is my html

echo "Choose Category:"; 
echo "<br/><select name=\"listing\">"; 
echo "<option value=\"\">Select Category</option>"; 
echo "<option value=\"career_jobs\">Career/Jobs</option>"; 
echo "</select><br/>"; 

echo "Choose state:"; 
echo "<br/><select name=\"state\">"; 
echo "<option value=\"\">Select state</option>"; 
echo "<option value=\"texas\">texas</option>"; 
echo "</select><br/>"; 

 

whenever i add the empty($listing) ||  my data is not entered into database and i get the all fields are must message

[Maq]

What's the error?

[$php_mysql$]

error message is my own error message

 

this

echo "All fields are must<br/>";

 

shows when i try to validate the select drop down filed

[$php_mysql$]

say by default it shows like this

 

 

echo "<option value=\"\">Select state</option>";

 

 

so if a user do not select the state value is empty when i try to validate it by adding empty($state) i get error

[WebStyles]

$ad and $location don't exist, to this:

 

empty($ad) || empty($location)

 

will throw the error

[$php_mysql$]

oh yes i missed that thanks, well i added them but still the i get error when i try to validate the drop down fields

[$php_mysql$]
