scm22ri Posted August 18, 2012 Share Posted August 18, 2012 In the below URL if a person chooses "what" or "whatever2" how would I get the price to adjust upwards or downwards based on what they choose? Would that be related to a mysql statement? Thanks man! For example, if they choose "whatever" the price goes up for 100 or "whatever2" the price goes down by 100. How would I do something like that? Thanks! http://whatsmyowncarworth.com/auto-members/math/math.php Quote Link to comment Share on other sites More sharing options...
Christian F. Posted August 18, 2012 Share Posted August 18, 2012 $priceMods = array ('whatever' => 100, 'whatever2' => -100); if (isset ($priceMods[$_POST['options']]) { $price += $priceMods[$_POST['options']]; } And if you're smart, then you'll use the same $priceMods array to build the dropdown selection.

scm22ri Posted August 19, 2012 Author Share Posted August 19, 2012 Hey Christian, Thanks for the code, I appreciate it but I keep on getting an error. It's a simple error but I can't seem to figure it out or where I should delete or move the {. Below is my syntax. What am I doing wrong? Thanks everyone! <?php //Connect to the database through our include include "connect_to_mysql.php"; // Query member data from the database and ready it for display $sql = mysql_query("SELECT price FROM car_data2"); while($row = mysql_fetch_array($sql)){ $price = $row["price"]; } ?> <?php $priceMods = array ('whatever' => 100, 'whatever2' => -100); if (isset ($priceMods[$_POST['choose']]) { $price += $priceMods[$_POST['choose']]; } ?> <html> <head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> <?php echo "$price"; ?> <form action="math.php" method="post" enctype="multipart/form-data" name="form" id="form" onSubmit="return validate_form ( );"> <table> <tr> <td>Choose:</td> <td> <select name="choose"> <option value="whatever">Whatever</option> <option value="whatever2">Whatever2</option> </select> </td> </tr> <tr> <td width="99"> <input type="submit" name="submit" value="Contact Us"> </td> </tr> </table> </form> </body> </html> Quote Link to comment Share on other sites More sharing options...

scm22ri Posted August 19, 2012 Author Share Posted August 19, 2012 Hey, I'm getting a parsing error. Parse error: syntax error, unexpected '{' in /home/scm22ri/public_html/whatsmyowncarworth.com/auto-members/math/math.php on line 25 I've tried a million times to rewrite the code but I don't know what I'm doing wrong. Error is turned on (you can't see that in my above syntax). Thanks! Quote Link to comment Share on other sites More sharing options...

If you haven't already figured it out, you need to close 1 of your parathensis: if (isset ($priceMods[$_POST['choose']]) { Should be: if (isset ($priceMods[$_POST['choose']])) { Quote Link to comment Share on other sites More sharing options...
