PHP - Simple Php From Validation
Hi, I am searching for a basic, easy to implement php form validation script that checks if the user has filled out a field, if they havent to tell them so.
i have tried basic if statements but it refreshes the page and all the other fields that were filled in are clear. Anyone know of any tricks or scripts that are good? Thanks in advance. Similar TutorialsHi Guys Simple question. Can anyone tell me why this doesn't work please? Code: [Select] $test = "<HEELOOOO"; $test2 = filter_var("$test", FILTER_SANITIZE_STRING); echo $test2; When I run this get I get nothing echoed back, not even in the source. So can the filter function not be used like this? I thought it would encode the special character and return it but I must be missing something simple here! Thanks, Drongo Not sure what I am missing. When submitted gives white page with no submission. Error check is not showing anything.

I'm having trouble with this form. I can't seem to figure out the rest of what is required I have already done most of it...I'm just stuck on these parts: Province Select : (AutoGeneration, Multiple Select, Memory) AutoGeneration using Provinces Array: The Province Select box is generated by PHP using this array: provinces.txt Cut and paste this array into your own code. Multiple Selections: Note that the province select box permits multiple values to be selected. View the HTML source to see the configuration details. Also note how $_POST delivers these multiple values as an array. Select Box Memory: The Province select box retains the user choices after a POST. For each province selected by the user, your code will generate the "selected" attribute in the <options> tag for that province. View the HTML source of the working solution to see how this works. Status CheckBoxes (Multiple Select, Memory) Multiple Selections: Note that these checkboxes have been configured in the HTML to permit multiple selections. Also note that $_POST delivers these multiple selection values in an array. Status Box Memory:The Status Box retains the user choices after a POST. Your code will need to generate the "checked" attribute in the <input> tag for each item selected. Do not generate the checkboxes with an array. Location Radio button: Do not generate the radio buttons with an array. The Location radio button retains the user choice after a POST. Validation Success Message: Where does it go - The final success message is placed within the <div class="success"></div> tags at the top of the HTML. Use a Loop: Generate the success message with a single array loop that reads the $_POST array and prints out the success message as an ordered list. Form Variables List Un-Ordered List - The form variables are displayed in an unordered list . CSS removes the bullet. Names Capitolised - The names of the form variables are capitolised ( use strtoupper() function ) . Handle Empty Values - Print "---None supplied---" if the variable is empty. Province Long Names - Print the long names of the provinces selected as comma separated string Status Choices - Print the status choices as a comma separated string. Functions I need to use: empty() - is the string empty. Unfortunately, a "0" value counts as an empty string. strlen() - returns the number of characters in a string. is_numeric() - is the string a number count() - how many rows in an array is_array() - is the variable an array isset() - does the variable or member of array exist in_array() -does this string exist in this array strtoupper() - convert string to upper case. join() - you'll want this one too. Converts an array of strings into a string with a delimiter. error_reporting(E_ALL ^ (E_NOTICE | E_WARNING)); - suppresses warning messages in your code. Place at top. foreach ($_POST as $KEY => $VAL) {} - walk through the $_POST array (or any array) My code: Code: [Select] <!--"StAuth10065: I Adam Graham, 000136921 certify that this material is my original work. No other person's work has been used without due acknowledgement. I have not made my work available to anyone else."--> <? $PROVINCES = array( "--" => "--- Please Select Provinces ---", "nf"=>"Newfoundland", "pe"=>"Prince Edward Island", "nb"=>"New Brunswick", "ns"=>"Nova Scotia", "qc"=>"Quebec", "on"=>"Ontario", "mb"=>"Manitoba", "sk"=>"Saskatchewan", "ab"=>"Alberta", "bc"=>"British Columbia", "nt"=>"Northwest Territories"); if ($_SERVER['REQUEST_METHOD'] == 'GET') { $dimwelcomeMsg = TRUE; } if ($_SERVER['REQUEST_METHOD'] == 'POST') { if ($_POST['uname'] == ''){ $errMsgs['uname'] = "Username must not be blank!!!"; $unameInError = true; } if (empty($_POST['year']) == TRUE){ $errMsgs['year'] = "Year must not be blank!!"; } if (count($errMsg) > 0 ): $dispErrorMsg = TRUE; else: foreach ($_POST as $key => $val): $key = strtoupper($key); $successMsg[$key] = $val; endforeach; $dispSuccessMsg = TRUE; endif; } ?> <html > <head> <title>Comp10065 - Simple Form Validatioon</title> <style type="text/css"> body { margin: 0; padding: 0; font: 80%/1.5 Arial,Helvetica,sans-serif; color: #111; background-color: green; } h2 { margin: 0px; padding: 10px; font-family: Georgia, "Times New Roman", Times, serif; font-size: 200%; font-weight: normal; color: #FFF; background-color: #CCC; border-bottom: #BBB 2px solid; } h1 {color:#006600} p#copyright { margin: 20px 10px; font-size: 90%; color: #999; } div.form-container { margin: 10px; padding: 5px; background-color: #FFF; border: #EEE 1px solid; } p.legend { margin-bottom: 1em; } p.legend em { color: #C00; font-style: normal; } div.errors { margin: 0 0 10px 0; padding: 5px 10px; border: #FC6 1px solid; background-color: #FFC; } div.errors p { margin: 0; } div.errors p em { color: #C00; font-style: normal; font-weight: bold; } div.success { margin: 0 0 10px 0; padding: 5px 10px; border: #FC6 1px solid; background-color: #FFC; } div.success p { margin: 0; color:#006633} div.success li {list-style-type: none; } div.form-container form p { margin: 0; } div.form-container form p.note { margin-left: 170px; font-size: 90%; color: #333; } div.form-container form fieldset { margin: 10px 0; padding: 10px; border: #DDD 1px solid; } div.form-container form legend { font-weight: bold; color: #666; } div.form-container form fieldset div { padding: 0.25em 0; } div.form-container label, div.form-container span.label { margin-right: 10px; padding-right: 10px; width: 150px; display: block; float: left; text-align: right; position: relative; } div.form-container label.error, div.form-container span.error { color: #000; } div.form-container select.error, div.form-container div.error {background-color: #FEF;} div.form-container label em, div.form-container span.label em { position: absolute; right: 0; font-size: 120%; font-style: normal; color: #C00; } div.form-container input.error { border-color: #C00; background-color: #FEF; } div.form-container input:focus, div.form-container input.error:focus, div.form-container textarea:focus { background-color: #FFC; border-color: #FC6; } div.form-container div.controlset {margin: 3px} div.form-container div.controlset label, div.form-container div.controlset input { display: inline; float: none; } div.form-container div.controlset div { margin-left: 170px; } div.form-container div.buttonrow { padding-left: 430px; border: 1px solid #CCCCCC } div#wrapper {width: 700px ; margin-left: auto; margin-right: auto} pre {color:black; font-size: 10pt; font-weight: bold; margin-left: 30px} </style> </head> <body> <div id="wrapper"> <h1> Form Validation Lab</h1> <div class="form-container"> <?

Cheers Hey everyone. I hope you can help me getting through this problem, because I have no idea of what else to try. I'm a web designer and sometimes modify Javascript, but my main focus is HTML and CSS, meaning I have no idea how to code in Javascript, but most importantly, how to write something from scratch in PHP. So I designed a form that works pretty well, and integrated a PHP and Javascript script to make it work. This is the form: Code: [Select] <form name="form" id="form" method="post" action="contact.php"> <p>Hello,</p> <p>My name is <input type="text" name="name">, from <input type="text" name="location">, and I'd like to get in touch with you for the following purpose:</p> <p><textarea name="message" rows="10" ></textarea></p> <p>By the way, my email address is <input type="text" name="email" id="email" placeholder="john@doe.com">, and I can prove I'm not a robot because I know the sky is <input type="text" name="code" placeholder="Red, green or blue?">.</p> <p title="Send this message."><input type="submit" id="submit" value="Take care."></p> </form> And this is the script, in an external file called contact.php: Code: [Select] <?php $name = check_input($_REQUEST['name'], "Please enter your name.") ; $location = check_input($_REQUEST['location']) ; $message = check_input($_REQUEST['message'], "Please write a message.") ; $email = check_input($_REQUEST['email'], "Please enter a valid email address.") ; if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email)) {die("E-mail address not valid");} if (strtolower($_POST['code']) != 'blue') {die('You are definitely a robot.');} $mail_status = mail( "my@email.com", "Hey!", "Hello,\n\n$message\n\nRegards,\n\n$name\n$location", "From: $email $name" ); function check_input($data, $problem='') { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); if ($problem && strlen($data) == 0) { show_error($problem); } return $data; } function show_error($myError) { ?> <html> <body> <b>Please correct the following error:</b><br /> <?php echo $myError; ?> </body> </html> <?php exit(); } if ($mail_status) { ?> <script language="javascript" type="text/javascript"> alert('Thank you for the message. I will try to respond as soon as I can.'); window.location = '/about'; </script> <?php } else { ?> <script language="javascript" type="text/javascript"> alert('There was an error. Please try again in a few minutes, or send the message directly to aalejandro@bitsland.com.'); window.location = '/about'; </script> <?php } ?> So what it does is this: if everything's OK, it sends an email with "Hey!" as the subject, "[name]" as the sender, "Hello, [message]. Regards, [name], [location]" as the body, and a popup saying the message was delivered appears. If something fails, it outputs the error in a new address, so the user will have to go back to the form and correct the error. What I actually want to happen is this: if everything's OK, a <p> which was hidden beneath the form appears saying the message was delivered, or, alternatively, make the submit button gray out and confirm the message was delivered. I found a script to make this happen, but with "Please wait...", so the user can't resubmit the form. If there's an error, I'd like another <p> which was hidden to appear with the specific error, so there'd be many <p>'s hidden with different IDs. If possible, I'd also like to change the CSS style of the input field, specifically changing the border color to red, so it'd be a change in class for the particular field. -- So in essence, I want the errors and the success messages to output in the same page as the form (without refresh), and a change of class in the input fields that have an error. Thanks in advance, and please let me know if it'll be possible. Hi everyone, I'm trying to select either a class or an id using PHP Simple HTML DOM Parser with absolutely no luck. My example is very simple and seems to comply to the examples given in the manual(http://simplehtmldom.sourceforge.net/manual.htm) but it just wont work, it's driving me up the wall. Here is my example: http://schulnetz.nibis.de/db/schulen/schule.php?schulnr=94468&lschb= I think the HTML is invalid: i cannot parse it. Well i need more examples - probly i have overseen something!

Edited by sam20e, 11 November 2014 - 10:31 AM. I need to validate first name, last name, street, suburb, postcode, email, status and date of birth. I tried to do this validation but gave me heaps of error and I messed up more. Spoiler
if (empty($firstname)) {$errors[] =" First Name Can not be Empty <br> ";}
if (empty($lastname)) {$errors[] =" Last Name Can not be Empty <br> ";}
if (empty($street)) {$errors[] =" Street Can not be Empty <br> ";}
if (empty($suburb)) {$errors[] =" Suburb Can not be Empty <br> ";}
if (empty($postcode)) {$errors[] =" Postcode Can not be Empty <br> ";}
// elseif (!is_numeric($postcode)) {$errors[] =" Postcode must be numeric ";}
elseif(!preg_match("/\^\(\[0\-9\]\{5\}\(\[\-\\s\]\?\[0\-9\]\{4\}\)\?\)\$/", $postcode)) {$errors[] =" Please enter a valid post number <br> ";}
if( !preg_match("/^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$/i", $myemail) ) {$errors[] =" You have entered and invalid email address <br> ";}
if (empty($DOB)) {$errors[] =" Date only <br> ";}
Hi there, I am working on getting my php form validation working. I just learned why mine wasn't working and it was because I had a header(location) in the middle of the html doc. The reason I had it there was because the code I am using is placed where I want the error to show. Here is the code I am using for this part. I only have one field being validated at the moment. Code: [Select] <? session_start(); if ($_POST['submit']) { $_SESSION['City'] = $_POST['City']; $errors = ""; if(!$_SESSION['City']){ $errors = $errors . "Please enter your city<br>"; } if ($errors != "") { echo "Please check the following errors:<br>"; echo $errors; } else { header("Location: nextpage.php"); } } ?> My question is: What way would you reorganize this (scrapy) validation to where I can redirect my user to a new page when there is no error value? The form page submits to itself with POST. Thanks for your help. |
