In this post we will and validate a simple form using HTML and PHP.<\/p>\n\n\n\n

Step 1<\/strong>: Create the html form using following code.<\/p>\n\n\n\n

<!DOCTYPE html>\n<html>\n<head>\n\t<title><\/title>\n<\/head>\n<body>\n <form  method=\"POST\" enctype=\"multipart\/form-data\" id=\"alumini-form\">\t\n\n Name <input type=\"text\" name=\"name\" value=\"\">\nAddress <input type=\"text\" name=\"address\" value=\"\">\nEmail <input type=\"text\" name=\"email\" value=\"\">\n<input type=\"radio\" name=\"howMany\" value=\"zero\"> 0\n<input type=\"radio\" name=\"howMany\" value=\"one\"> 1\n<input type=\"radio\" name=\"howMany\" value=\"two\"> 2\n<input type=\"radio\" name=\"howMany\" value=\"twoplus\"> More than 2\n<select name=\"favFruit[]\" size=\"4\" multiple>\n <option value=\"apple\">Apple<\/option>\n <option value=\"banana\">Banana<\/option>\n <option value=\"plum\">Plum<\/option>\n <option value=\"pomegranate\">Pomegranate<\/option>\n <option value=\"strawberry\">Strawberry<\/option>\n <option value=\"watermelon\">Watermelon<\/option>\n<\/select>\n<input type=\"checkbox\" name=\"brochure\" value=\"Yes\">\n<input type=\"submit\" name=\"submit\" value=\"Submit\">\n\n<\/form>\n\n\n\n<\/body>\n<\/html><\/code><\/pre>\n\n\n\n
Step 2:<\/strong> Please use the following code to validate the php forms. You can add the below code before html code.<\/p>\n\n\n\n
if ($_SERVER[\"REQUEST_METHOD\"] == \"POST\") {\n    if (empty($_POST[\"name\"])) {\n        $nameErr = \"Missing\";\n    }\n    else {\n        $name = $_POST[\"name\"];\n    }\n\n    if (empty($_POST[\"address\"])) {\n        $addrErr = \"Missing\";\n    }\n    else {\n        $address = $_POST[\"address\"];\n    }\n\n    if (empty($_POST[\"email\"]))  {\n        $emailErr = \"Missing\";\n    }\n    else {\n        $email = $_POST[\"email\"];\n    }\n\n    if (!isset($_POST[\"howMany\"])) {\n        $howManyErr = \"You must select 1 option\";\n    }\n    else {\n        $howMany = $_POST[\"howMany\"];\n    }\n\n    if (empty($_POST[\"favFruit\"])) {\n        $favFruitErr = \"You must select 1 or more\";\n    }\n    else {\n        $favFruit = $_POST[\"favFruit\"];\n    }\n}<\/code><\/pre>\n\n\n\n
