PHP - Javascript Vs Php For Form Validation?
Let's say I have a form with 5 fields to fill out
Is it better practice to use Javascript to ensure that all fields are non-empty, a certain length, contain certain characters, etc. Or should the back end PHP side of things handle this, then return an error code to be printed out, etc Thanks! Similar TutorialsI'm a major JS noob and this is driving me nuts. I'm trying to use this in a form:

And using the examples, can't get anything to work. Only my browser's non-js HTML 5 form validation. Anybody have a simple that incorporates both HTML and JS? The examples only show the html.
This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=342898.0 I am working on a PHP project that will allow a user to upload a handful of images, and then submit text to go along with it. To simplify the uploading process of a file, I restricted the type of file that can be uploaded (jpg) and the size (2.5mb). The problem is, the form is calling to a PHP script, and I have error logging built in to alert the user of why a file didn't upload, but since the PHP script is just being called, no errors are being displayed on the page. I guess unless I do a refresh of a few seconds to view any errors on the page.... What I would like to do is show a pop-up/error message notifying the user that the file type or size is incorrect and needs to be adjusted. Now part of the problem is, the file needs to be uploaded to the server first, and then everything can be checked, so I am really getting confused. If someone can point me in the right direction on what I could use to accomplish this, it would be greatly appreciated. Thanks -beemer hey everyone, on my site I have a form, is there any reason I should use php validation vs javascript validation ? thanks Okay with some help I was able to create a working guestbook! How ever I need a bit of help with validation. I would like to have it so that when someone doesn't fill out a required field a message is displayed next to the improperly filled out field. How would I go about adding this to my form or process code? So for example: if someone doesn't fill out the "name" field and clicks "sign" it will not submit but instead will display a message such as "Please fill out your name" next to the form field. Also will I am here I wanted to ask. How can I make it so that when a non-required field is left empty and posted it will fill that section out with default text? So for example: if someone decides they do not wish to fill out the "Favorite part of my site" or "Favorite Pat Song" field than submits the form than it will fill that section with a default message like this: Posted by: someone (someone@domain.com) 2011/04/09 Favorite Pat Song: -- Favorite Part of the Site: -- comments here And I promise this is my very last question. I would like for email to be required but would like to allow the user to decide whether it is kept private or not. How do I make it so that when someone doesn't type their email in it does like what I stated above, it will show a message next to the field telling them to fill out a valid email but also if they select to keep their email private it will than post a default value in place of where the email would have been. for example: if the email field is left empty or is an invalid email it will display a message such as "Please fill out a valid email address" next to the form field. and than if they do so but also check the "private" box it will post their message in the guestbook with a default value in place of the email like this: Posted by: someone (Private) 2011/04/09 Favorite Pat Song: -- Favorite Part of the Site: -- comments here so that was a lot here's my guestbook code: Code: [Select] <?php <span style='color:#ff0000'><b>*</b></span><span> = required field</span><br /><br /> <form name='guestbook' action='process.php' method='post'> <table width='550' border='0' cellspacing='2' cellpadding='0'> <tr valign='top'> <td width='550px' class='what'><span style='color:#ff0000'><b>*</b></span> Your Name:</td> <td width='550px'><input name='name' type='text' id='name' size='32' /></td> </tr> <tr valign='top'> <td width='550px' class='what'><span style='color:#ff0000'><b>*</b></span> Email Address:</td> <td width='550px'><input name='email' type='text' id='email' size='32' /><input type='checkbox' name='private' value='Private' />Private</td> </tr> <tr valign='top'> <td width='550px' class='what'>Your Favorite Pat Song?:</td> <td width='550px'><input name='song' type='text' id='song' size='32' /></td> </tr> <tr valign='top'> <td width='550px' class='what'>Your Favorite Part of my Site?:</td> <td width='550px'><input name='part' type='text' id='part' size='32' /></td> </tr> <tr valign='top'> <td width='550px' class='what'><span style='color:#ff0000'><b>*</b></span> Comment:</td> <td width='550px'><textarea name='comments' cols='28' rows='6' id='comments' class='bodytext'></textarea></td> </tr> <tr> <td class='bodytext'> </td> <td align='left' valign='top'><input name='submit' type='submit' class='btn' value='Sign' /></td> </tr> </table> </form>"; }else{ $connect = mysql_connect("127.0.0.1","patben_admin","pepsi_1990") or die('Error connecting'); $db = mysql_select_db("patben_db") or die('Error selecting db'); $query = mysql_query("SELECT * FROM guestbook order by id desc"); $num_rows = mysql_num_rows($query); if($num_rows > 0) { //display entries while($row = mysql_fetch_array($query)){ echo ' <table> <tr> <td> <b>Posted by:</b> '.$row['name'].'

Any help would be greatly appreciated! Thank you Hi. I'm new to PHP and have a problem with some form validation. The code below is my contact form. It was working until I added a dropdown list and checkbox. For all the other fields I created an input variable using the 'name' attribute to reference the data entered into the input fields and the validation appeared to work and an email was sent to the appropriate email address. For the checkbox field I have also created a 'name' attribute but don't know whether this is right way to confirm whether the box has been checked? For the field with a dropdown selection I have used the option 'selected', but again, don't know whether this is right or not. Now when I enter valid data into all the fields, select a value from the dropdown and check the checkbox, I get an error message stating that I need to fill in all the form fields. I am pretty sure it is to do with the way I have tried to pick up the data from dropdown list and the checkbox, but can't figure out what it is. Any help would be much appreciated. Thanks in advance.

I am asking for some simple help, please. :-) I have a form that I would like to validate very specific information on - without having it validate in the php and loose what the client just put into the site. I have found an example in this "validation" process. However, when I open this up in Dreamweaver CS4, I have an error on line 67 as a syntex error. I am unable to see where this would be. All I need is a verification on the name, the phone number, and the email address. Here is what I have so far.... **This is contact form** Code: [Select] <script language="JavaScript"> function checkForm() { var cname, cemail, cphone with(window.document.Contact1) { cname = name; cemail = EmailFrom; cphone = phone; } if(trim(cname.value) == '') { alert('Please enter your name'); cname.focus(); return false; } else if(trim(cemail.value) == '') { alert('Please enter your email'); cemail.focus(); return false; } else if(!isEmail(trim(cemail.value))) { alert('Email address is not valid'); cemail.focus(); return false; } else if(trim(cphone.value) == '') { alert('Please enter message subject'); csubject.focus(); return false; } } else { cname.value = trim(cname.value); cemail.value = trim(cemail.value); cphone.value = trim(cphone.value); return true; } } function trim(str) { return str.replace(/^\s+|\s+$/g,''); } function isEmail(str) { var regex = /^[-_.a-z0-9]+@(([-_a-z0-9]+\.)+(ad|ae|aero|af|ag| ai|al|am|an|ao|aq|ar|arpa|as|at|au|aw|az|ba|bb|bd|be|bf|bg| bh|bi|biz|bj|bm|bn|bo|br|bs|bt|bv|bw|by|bz|ca|cc|cd|cf|cg| ch|ci|ck|cl|cm|cn|co|com|coop|cr|cs|cu|cv|cx|cy|cz|de|dj|dk| dm|do|dz|ec|edu|ee|eg|eh|er|es|et|eu|fi|fj|fk|fm|fo|fr|ga|gb| gd|ge|gf|gh|gi|gl|gm|gn|gov|gp|gq|gr|gs|gt|gu|gw|gy|hk|hm|hn| hr|ht|hu|id|ie|il|in|info|int|io|iq|ir|is|it|jm|jo|jp|ke|kg| kh|ki|km|kn|kp|kr|kw|ky|kz|la|lb|lc|li|lk|lr|ls|lt|lu|lv|ly| ma|mc|md|mg|mh|mil|mk|ml|mm|mn|mo|mp|mq|mr|ms|mt|mu|museum| mv|mw|mx|my|mz|na|name|nc|ne|net|nf|ng|ni|nl|no|np|nr|nt|nu| nz|om|org|pa|pe|pf|pg|ph|pk|pl|pm|pn|pr|pro|ps|pt|pw|py|qa| re|ro|ru|rw|sa|sb|sc|sd|se|sg|sh|si|sj|sk|sl|sm|sn|so|sr|st| su|sv|sy|sz|tc|td|tf|tg|th|tj|tk|tm|tn|to|tp|tr|tt|tv|tw|tz| ua|ug|uk|um|us|uy|uz|va|vc|ve|vg|vi|vn|vu|wf|ws|ye|yt|yu|za| zm|zw)|(([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5])\.){3}([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5]))$/i; return regex.test(str); } </script> Below is the php file that I am using....

Again - when I open up Contact1.html in DW CS4, I get a syntext error on line 67. When I use just straight form, it opens to new window with php - > error.html, which in turns looses everything the client just typed. Any help is greatly appreciated and thank you in advance. Blessings! If asked, I can attach the files if needed as well, but the code is pretty self-explain. Hi I am currently writing code to validate a form using PHP. What i wanted was to validate all inputs and then post the data to a external mysql server.

I was wondering if I could have some help with some form validation. In my insert script, I have: <label for="text"><br /> <br /> Question Text:</label> <textarea name="text" id="text" cols="45" rows="5"> </textarea> Then in a separate script, I input the data into a database: $data = array('text' => $_POST['text'] 'question_type' => $_POST['question_type'], 'solution' => $_POST['solution'], 'author_id' => $_POST['author'], 'public_access' => $_POST['public_access']); In this database script, I'd like to check if the text field was "posted": if it's empty I'd then like to print "Required field" on my original script. First, if there's nothing to be posted from the text field, I want to stop the database script and return before entering a blank field into my database. Then, it would be great if I could print a "Required field" message in the original script. Thanks in advance for your help! How can I go about validating a form in PHP? I am trying to do so, but I am clueless as to how to structure it. Hi all, Im trying to add validation to a form to allow PHP to check before its sends the values to another page for them to be uploaded to a database. The problem i have is that i have taken a, i thought simple PHP validating script off the net and i cant seem to get it to work, its just giving me a blank page. I dont know if the script is outdated, i dont think it is. The script is he Code: [Select] <?php include("validation.php"); ?> <!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;

I want in my form to validate on the fly(when the user enters the user name) to validate if the user name exists or not.

<div class="contact"> Hi Guys, Im a bit of a novice to Php but somehow I've managed to get myself a form together for customers to book online. My problem is that i need to validate all the input's of my form. To give you some idea of what i mean. The $name should only contain letters and be no longer than 25 characters. The $address should only contain letters & numbers and be no longer than 40 characters. The $district and $town should only contain letters and be no longer than 30 characters each. The $postcode should only contain letters and Numbers and be no longer than 8 characters, it should start and end with a letter if thats possible. The $phone should only contain numbers and be no longer than 11 characters. And the email, well im lost with how that should be set out because of all the different options you can have. Anyway, this is my code: <?php $to = 'myemail.com' ; $from = $_REQUEST['Email'] ; $name = $_REQUEST['Name'] ; $phone = $_REQUEST['Phone']; $headers = "From: $from"; $subject = "Booking Request"; $fields = array(); $fields{"Name"} = "Name"; $fields{"Address"} = "Address"; $fields{"District"} = "District"; $fields{"Town"} = "Town"; $fields{"Postcode"} = "Postcode"; $fields{"Phone"} = "Phone"; $fields{"Email"} = "Email"; $fields{"list"} = "Mailing List"; $fields{"Message"} = "Message"; $body = "We have received the following information:\n\n"; foreach($fields as $a => $b) { $body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]); } if ($name == '') {print "You have not entered a name, please go back and try again";} elseif ($phone == '') {print "You have not entered a Phone number, please go back and try again";} else { $send = mail($to, $subject, $body, $headers); if($send) {header( "Location: http://www.(not applicable).com" );} else {print "We encountered an error sending your mail, please notify webmaster@YourCompany.com"; } } ?> Any help is greatly apprecaited. Kind regards Rich I'm trying to get validation messages to display on the same page as my login form without any PHP within my login page, is that possible?
Hi, I currently have the following code in my form processing script: Code: [Select] $string_exp = "/^[A-Za-z .'-]+$/"; $error_missing = 'This field is required'; if(!preg_match($string_exp,$Name)) { $errors[] = $error_missing; } if(!preg_match($string_exp_number,$Phone)) { $errors[] = $error_missing; } if(is_array($errors)) { echo 'Your message could not be sent due to the following errors:'; while (list($key,$value) = each($errors)) { echo '<span class="error">'.$value.'</span><br />'; } If the user enters no data into the required fields, the script prevents the form from being submitted and displays an error. At present the errors for all the required fields are displayed in a long list at the top of my HTML form e.g. This field is required This field is required What I want to do, is place the error message under each required field e.g. this http://coreyworrell.com/assets/uploads/images/ajax_contact_form.png instead of this http://cdn1.1stwebdesigner.com/wp-content/uploads/2010/02/validation-ajax-css-form.jpg What do I need to do? My form looks similar to this at the moment: Code: [Select] <div id="log"> <div id="log_res"> </div> </div> <form id="contact" name="contact" method="post" action="process.php"> <label>Name</label> <input type="text" name="Name" id="Name" tabindex="1" /> <label>Email</label> <input type="text" name="Phone" id="Phone" tabindex="2" /> </form> The error messages are placed in the <div> section at the top of the form (using ajax) |
