PHP - How To Declare $_post In Oop

please help me. thanks. Similar TutorialsHowdy colleagues,
I have noticed some programmers re-declare their variables before using them. Like so:
$name = ''; $name = 'Elizabeth';First of all, why do they do that? Variables are being re-written with each "=" anyways. Secondly, do you believe this is better than just doing: $name = 'Elizabeth';Thank you Can you set a variable like so: Function something(bob = true) { } I'm started learn PHP about 7 days.I want to know>>is this possible to declare a Variable like $password="Phpfreaks"??? hi, cane somebody please explain how to use the declare contruct of PHP some code snippets may help..thanks in advance According to woorank.com my page shows the following.

I keep running into a bunch of error when I declare the page variable in my model. What syntax do I need to use throughout the class? Code: [Select] <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Header_Model extends CI_Model{ var $page = substr(end(explode(DIRECTORY_SEPARATOR, $_SERVER['PHP_SELF'])), 0, -4); function get_page_name() { $this->load->library('common'); $page_names = $this->common->page_names(); $title = (array_key_exists($page, $page_names) !== false) ? $page_names[$page]: ''; if (array_key_exists($page, $page_names) !== false) { $title .= " | Jason Biondo"; } return $title; } function get_js_page_file() { if (file_exists("./assets/js/pages/${page}.js")) { $javascript = "<script type=\"text/javascript\" src=\"./js/pages/${page}.js\"></script>"; } return $javascript; } } Hi, I have these variables for pages I navigate to because I pass them in the query string. However, I need a variable for the homepage (index.php), before any query string is created. I cant declare a vari $_GET['intro'] ; $_GET['about'] ; $_GET['contact'] ; However, I need a variable for the homepage (index.php), before any query string is created. I cant declare a variable in index.php because it will be used throughout the entire website. I also cant declare the variable in home.php (the bulk content of the homepage) because I need to use the variable before home.php is included. Is their a trick for this? Thanks! I tried these below, Code: [Select] class Site extends Controller { function Site() { public $data = Array(); } } but it fail? Thanks in advanced. I am running through a tutorial and I am getting an error based on a the concatication operator on my output. Below is my code. As you can see I am echoing $display_block .= "<p>$title<br>$rec_label<br>.... If I send this as-is I get this error: Notice: Undefined variable: display_block in C:\wamp\www\php\php_mysql\sel_byid.php on line 36 I can resolve the error by placing this before the while loop: $display_block = ""; Is there a better way to output the concatenation.= so I don't need to do this weird fix? while ($row = mysql_fetch_array($result)) { $id = $row['id']; $format = $row['format']; $title = stripslashes($row['title']); $artist_fn = stripslashes($row['artist_fn']); $artist_ln = stripslashes($row['artist_ln']); $rec_label = stripslashes($row['rec_label']); $my_notes = stripslashes($row['my_notes']); $date_acq = $row['date_acq']; if ($artist_fn != "") { $artist_fullname = trim("$artist_fn $artist_ln"); } else { $artist_fullname = trim("$artist_ln"); } if ($date_acq == "0000-00-00") { $date_acq = "[unknown]"; } $display_block .= "<p>$title<br>$rec_label<br>$artist_fullname<br>$my_notes<br>$date_acq<br>$format</p>"; I use a form to sent date and use php to display it .

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"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$x" in D:\Apache Software Foundation\Apache2.2\htdocs\.....\#####.php on line 20 Notice: Undefined index: "rim"."$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?

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 Edited by AdamHull12, 04 October 2014 - 11:15 AM. 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. I have a button that uses $_POST to send information to another page. The data is in a hidden input so it's not possible for users to change information. I have nothing to check if the data is correct on the other page. Is it still possible for people to change the $_POST data though? Or somehow send false $_POST data to the other page? Hey, I have a database with user info in it. I was wondering would it be possible to have a link post info to a page and then have that page display info relevant to the received info?... Link page: <a href="profile.php?name=<? print $_GET['Username'] ?>" method="post"><? $row['Username'] ?></a> Profile page: <?php $username = $_POST['Username']; $query = $query = mysql_query('SELECT * FROM users WHERE Username') ?> You are viewing: <? echo $username ?>'s profile. Email: <? echo $row['Email'] ?> I have predefined $row. Is it possible to do this way or would I have to use a different method?... Cheers |
