Hi there, im trying to get value from form to PHP but its not working.

 

 

 

 

<?php

 

 

if (isset($_POST['cartype'])==0)

{

 

echo("Please select car type.");

}

else if (isset($_POST['carcolour'])==0)

{

 

echo("Please select car colour.");

}

else if (isset($_POST['carenginesize'])==0)

{

 

echo("Please select car engine size.");

}

else if (isset($_POST['terms'])==0)

{

 

echo("Please agree to site terms and conditions before submitting your order.<br/>

 

Press the back button in your browser to try again.");

}

 

else{

 

 

 

 

$name=$_POST['firstname'];

$lastname=$_POST['lastname'];

$email=$_POST['emailaddress'];

$phone=$_POST['phone'];

 

$ctype=$_POST['cartype'];

$colour=$_POST['carcolour'];

$enginesize=$_POST['carenginesize'];

$options=$_POST['options'];

 

 

echo "Dear,"."$name"."$lastname";

echo "<br/>Thank you for your order";

 

 

echo "<br/>You're contact details are:-";

echo "Phone : "."$phone";

echo "email: "."$email";

 

echo "<br/>You have selected the following car:";

echo "<br/>Car type:"."$ctype";

echo "<br/>Colour:"."$colour";

echo "<br/>Engine size:"."$enginesize";

echo "<br/>Options:<br/>";

 

 

 

$count=count($options);

 

for($i=0;$i<$count;$i++)

{

 

echo $options[$i]."<br/>";

 

 

}

 

 

$optn=array("6 disc DVD changer",

"TV function",

"DAB digital radio",

"Loudspeaker system - professional ",

"Multimedia navigation system",

"Universal remote control",

"Voice control",

"Navigation system",

"Head-up display",

"Adaptive headlights",

"Night vision with pedestrian recognition",

"Run-flat tyres");

 

foreach($options as $optn)

{

echo "NEw option  ".$optn."<br/>";

 

 

}

 

 

 

 

}

?>

You'd better go for a different approach on error handling. As you have it, you show just one error, even if there are more. Take a look:

 

<?php
//check if the form has been submitted
//$_POST['submit'] is the post value of the submit button (if you have one)
if (isset($_POST['submit'])) {
     $errors = array();
     if ($_POST['cartype'] != '') { $errors[] = 'Please select car type'; }
     if ($_POST['carcolour'] != '') { $errors[] = 'Please select car colour'; }
     //and so on for every input you need validated

     //if no error occurred, process the form
     if (count($errors) == 0) {
          //process the form
     } else {
          //print errors
          foreach ($errors as $error) {
               echo $error . '<br />';
          }
     }
}
?>

 

Also, keep in mind that isset() checks if a variable exists. In the case of POST, variables will be created and return true to isset(), even if they're empty. It's better to check for length with strlen() or value.

You can use data from a drop-down in the same way as in other form elements. In your case:

 

<select name="options">
     <option value="1">6 disc DVD changer</option>
     <option value="2">TV function</option>
     <option value="3">DAB digital radio</option>
</select>

<?php
echo $_POST['options'];
?>

 

The selected value of the drop-down will be echoed. You don't need to treat the <select> as an array (name="options[]") because it can return just one value. You will need that instead when working with checkboxes.
