freakunleash Posted February 6, 2011 Share Posted February 6, 2011 Hi All, Need help with PHP output from HTML form. I don’t know if I’m doing it correctly or not. I have a form which ask to input data and output values in different page. It has multiple input field for same value and its value is stored in an array. If I submit the form PHP is calculating the empty fields also. I don’t want it to display values if there is no input. Below is the PHP and HTML code of one field. PHP Code <?php if(isset($_POST['product'])) { $product = $_POST['product']; $n = count($product); $i = 0; echo "Your selected Products are \r\n" . "<ol>"; while ($i < $n) { echo "<li>{$product[$i]}</li> \r\n"; $i++; } echo "</ol>"; } ?> HTML FORM <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Product details</title> <style type="text/css"> body { background-color: #C9F; } </style> </head> <body> <b> <h1>Create new Product entry:</h1> <form id="form1" name="form1" method="post" action="submit1.php"> <p>Product:<br /> <label for="product"></label> <input name="product[]" type="text" id="product" size="15" /> <input name="product[]" type="text" id="product" size="15" /> <input name="product[]" type="text" id="product" size="15" /><br /> <input name="product[]" type="text" id="product" size="15" /> <input name="product[]" type="text" id="product" size="15" /> <input name="product[]" type="text" id="product" size="15" /> <br /> <input name="submit" type="submit" id="send" value="submit"> </form> </b> </body> </html> Quote Link to comment Share on other sites More sharing options...
