Why Add $_post At The End Of A Validation Function?	View Content

Hi,

I was going to through a PHP tutorial, and came across a form validation user defined function . Below is an example..

Code: [Select]
function check_required_fields($fields){
$field_errors = array();
foreach ($fields as $requried_fields) {
if (!isset($_POST[$requried_fields]) || (empty($_POST[$requried_fields]) && $_POST[$requried_fields] != 0))
if (!isset($_POST[$fieldname]) || (empty($_POST[$fieldname]) && $_POST[$fieldname] != 0))
{
$errors[] = $requried_fields;
}
}
return $field_errors;
}
When the user defined function was called they added an $_POST and the end of the user defined function. Here is a the code snipped of how it looks

Code: [Select]
$errors = array();

// perform validations on the form data
$required_fields = array('username', 'password');
$errors = array_merge($errors, check_required_fields($required_fields, $_POST));
If the validation can be preformed with out the $_POST, why bother inserting it?

Thanks!

$_post Won't Work!! Form Validation Php/html

Hi there. My problem is quite simple, but carries lots of questions of why the hell is this happening.

I'm new at PHP but I'm familiar with the syntax, since It's been 3 years since I code in C, 1 in Java and half year in JS (with HTML and CSS of course).

I was creating a page where I could validate a HTML form using PHP script, it was going everything allright, until I couldn't use the data that was going to the $_POST array. I tested it on some other file and It was like the server just didn't allowed me to do it so. I searched around on internet and I found the print_r() function, which shows the data as an associative array in $_POST, like this: array(KeyName => ValueName).

Check the code and please, help me find why is this happening. I'm brazillian and all I know about english came from netflix, so i'm sorry if I wrote anything wrong. Thanks S&Z

Hello,

its a bit difficult to explain the issue that I have but I will try my best.

I have this small code $message = $_POST['message1']; in my php code and message1 is the name of a textarea in my page.

i also have another textarea called message2 in my page.

what I need to do is to use the message1 and message2 in the $message = $_POST function.

For example: $message = $_POST['message1'] + $_POST['message2'] or anything that is acceptable in PHP coding and works in PHP.

I hope I havent confused you guys and you undersstood what I mean...

Thanks

_post And Ip Address Collection Function

Similar Tutorials

I have a basic form for collecting data, I have a function for collecting the ip address of the visitors unfortunately I cannot get the ip collection working with the rest of the form once I put the if($_POST['emailaddress']) {.........} in.

My aim is once the user has completed the form, data gone to MySQL database that the data will then be printed via the echo statements on to the form as the action sends it back to the same page.

Currently my code is

<?php
/*
This script is a form handler, each section is commented as to what it does.
1. connects to the database (see connect.php).
2. it gets the users ip address.
3. Strips tags from the data entered so that no malicious code can be entered and corrupt/cause problems with the database or site.
4. Inserts the relevant data into the database in this case it is the ip, haveemail, emailaddress, browser, otherbrowser, resolution, otherresolution.
5. Sends the data just entered by the user back to the screen so they can see what they entered
*/

// 1. connection to MySQL
require ("php/connect.php"); // if this script is unavailable then the rest of the code is pointless as need a connection to the database.

// if fields are completed
if($_POST['emailaddress'])
{ // if this field has had data entered then process the data

// 2. collect ip address
//$ip = getRealIpAddr();

// 3. Strips tags and POST variables from the form
$haveemail = strip_tags($_POST['haveemail']);
$emailaddress = strip_tags($_POST['emailaddress']);
$browser = strip_tags($_POST['browser']);
$otherbrowser = strip_tags($_POST['otherbrowser']);
$resolution = strip_tags($_POST['resolution']);
$otherresolution = strip_tags($_POST['otherresolution']);

// 4. insert data to dbase
$query="INSERT INTO datacollection1 (id, ip, haveemail, emailaddress, browser, otherbrowser, resolution, otherresolution) VALUES ('Null', '$ip', '$haveemail', '$emailaddress', '$browser', '$otherbrowser', '$resolution', '$otherresolution')";

// Null is in the id field as this is added automatically in the database as it is set to auto increment upon an entry going in and is primary key.

// message to say if database has been updated

mysql_query($query) or die (mysql_error());

//echo "<b>Your IP address is: $ip</b> <br />";


/*function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
} */

// 5. displays information on form to advise what the user just entered
echo '<br/>'."The database has just been updated with the following information: ".'<br/><br/>';
// echo "Your ip address is ".$ip.'<br/>';
echo "You answered ".$haveemail." to having an email address.".'<br/>';
echo "Your email address is ".$emailaddress.'<br/>';
echo "You use ".$browser." to browse the internet".'<br/>';
echo $otherbrowser.'<br/>';
echo "Your screen resolution is set at ".$resolution.'<br/>';
echo $otherresolution.'<br/>';
echo "Now you have completed this form, please follow onto the main form, this form seeks to get your valuable opinion regarding your likes and dislikes of the websites researched.";
}

mysql_close($db); // closes the database, this is good practice but the database will close once stopped running.

?>

I have tried moving the function outside of the if($_POST['emailaddress']) but it still didnt get the ip address.

Just as a side note everything else works, the data is written into the database bar the ip address.

I would appreciate some help

Thanks in advance.

Email Validation Within A Function

Hello i have a syntax issue in the code below, can anyone shed some light?

Code: [Select]
<?php if(isset($_POST['submit']))
{
$drop = mysql_real_escape_string($_POST['drop_1']);
$tier_two = mysql_real_escape_string($_POST['Subtype']);
echo "You selected ";
echo $drop." & ".$tier_two;
$Name = mysql_real_escape_string($_POST["Name"]);
$Phone = mysql_real_escape_string($_POST["Phone"]);
$Email = mysql_real_escape_string($_POST["Email"]);
$Postcode = mysql_real_escape_string($_POST["Postcode"]);
$Website = mysql_real_escape_string($_POST["Website"]);
if($Name == '' || $Phone == '' || $Email == '' else if (!preg_match('/^[A-Za-z0-9\-.]+$/', $domain)||
$Postcode == '' || $Website == '')
{
die('<br> but you did not complete all of the required fields correctly, please try again');
}
}
the code works fine without the " else if (!preg_match('/^[A-Za-z0-9\-.]+$/', $domain) " .
As well as checking for blank fields i'd like to check for the correct email format.

Many thanks.

$_post Help

Hi guys, running through this tutorial at the moment:

http://www.tizag.com/phpT/forms.php

I seem to keep having problems with the $_POST variable. Is that obsolete syntax now?

Here's the part I get an error on:

<html>
<body>
<?php
$quantity=$_POST['quantity'];
$item=$_POST['item'];

echo "You ordered".$quantity."".$item.".<br/>.";
echo "Thank you for ordering from Boombaby art supppplies!";

?>
</body>
</html>

Here's the error:

( ! ) Notice: Undefined index: quantity in C:\wamp\www\process.php on line 4
Call Stack
#   Time   Memory   Function   Location
1   0.0009   363936   {main}( )   ..\process.php:0

You ordered.
.Thank you for ordering from Boombaby art supppplies!

Any help would be appreciated. I tried googling but everything didn't seem to answer my question or was too confusing.

Thanks.

Php $_post[' ']

Hi guys,

I have a form using radio buttons.
For the radio button, lets just say i have the id name as 'rim' + number eg; rim0, rim1, rim2....

When i post the data to another file to execute the data collected, naturally i would use the:
Code: [Select]
$rim0=$_POST['rim0'];
$rim1=$_POST['rim1'];
....
$rim10=$_POST['rim10'];
i tried to shorten this process using this method:
Code: [Select]
//$q is part of the post variable.
for($x = 0; $x < count($q); $x++){

$rim[]=$_POST['"rim"."$x"'];
}
But i get this error
Code: [Select]
Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20
Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20

Is there something wrong with my POST syntax?

$_post Not Grabbing The Value?

Similar Tutorials

I think this belongs here, but my $_POST['gender'] won't grab the gender that was submitted through a form.

I am using AJAX so the page doesn't have to reload so it can go in a smooth transition, but the AJAX is grabbing the value perfectly fine.
I have a feeling the $_POST isn't grabbing the value because the page isn't reloading.. but I don't want to reload it.
These codes are all on the same page.

Here is my Javascript:
Code: [Select]
<script>
function chooseGender()
{
var gender = $('input[name=gender]:checked', '#submitgender').val();
if(gender)
{
$.ajax(
{
type: "POST",
url: window.location.pathname,
data: gender,
success: function()
{
alert("You have chosen to be a " + gender); //It's grabbing it perfectly fine!
$("#submitgender").hide(); //It hides the gender table so they can't choose a gender since they already have chosen one.
$("#rest").fadeIn(); //Shows the other table that's labeled "rest" as it's ID so they can choose what base, eyes, etc for that specific gender they've chosen.
}
});
}
else
{
alert('Select a gender.');
}
}

$(function tabs()
{
$( "#tabs" ).tabs();
});
</script>
But here is the PHP inside the #rest table:
Code: [Select]
<?php
$gender = $_POST['gender'];

$sql = "SELECT * FROM habases WHERE gender='".$gender."'";
$result = mysqli_query($cxn, $sql) or die(mysqli_error($cxn));
print_r($sql);
while ($row = mysqli_fetch_assoc($result))
{
$baseimage = $row['image'];
$baseskin = $row['skin'];

echo "<img src=\"http://www.elvonica.com/".$baseimage."\" value=\"".$baseskin."\">";
}
?>
And this is what I'm getting for the print_r:
Quote

SELECT * FROM habases WHERE gender=''

How do I post data when a user clicks a link?

I know that for a submit button you just use the name attribute, but I'm not sure how to do it with a link.

Isset($_post)

Similar Tutorials

Running into some problems with my code. I am having the user search the Database with either a UAID or the user's full name. It works fine when you input both the UAID and name; however, I want it to work if only one is give (i.e. just the name or just the UAID).

I decided to use the isset($_POST) function of php but I am not getting it to work correctly. PHP believe it is set even though it is empty.

Securing $_post

Similar Tutorials

Hello, I am quite new to the php and website scene and i am trying to find the best way to validate and sterilize my $_post the way i have come up with is

$id = filter_var(mysql_real_escape_string($_POST['id']),FILTER_SANITIZE_NUMBER_INT);

or

$id = mysql_real_escape_string($_POST['id']);
$id1 = filter_var($id,FILTER_SANITIZE_NUMBER_INT);

which will be the best way to do it or is there a better way. Thanks
