PHP - Retrieving Checkbox Value Within Php
Hi,
so i have a problem. I'm using a script to enable and disable checkboxes, and i'm id-ing them fetching values from a database: while($data = mysqli_fetch_array($sql)) { if ($count % 5 == 0) { echo '</tr><tr>'; $count = 0; } echo '<td><input name="subject_level[]" class="subject_a" disabled="disabled" type="checkbox" id="subject_level_'.$data['subject_level_id'].'" value="'.$data['subject_level_id'].'"/>'; echo '<label for="subject_level_'.$data['subject_level_id'].'" class="subject_1">'.$data['subject_name'].'</label></td>'; $count++; //Increment the count } The names of the checkboxes come out fine, just that, is there any way to retrieve the values of the checkboxes into an array of some sort so that i could build a search query later? if($_POST(subject_level)) or if($_POST(subject_level[])) doesn't return true. does it make sense? im new to php so please forgive my ignorance. Help appreciated. Thanks!

The code I am using works (ie. returns the HTTP response) for any URL that I use except the one that I need! The URL is below, and when using that I get a blank response every time. I've tested and can telnet to that IP address on that port from my server. I'm not sure if it is because of the format/structure of the URL? Could it have something to do with the port of the gateway?

However, I'd like to be able to echo the email address used on their account.
I've tried adding the email to the session I'm not having much luck... Here's a piece of the login code(untouched);

Any Help in the right direction or some code would be appreciated? There's many options available for downloading a URL - but I'm stuck. I've looked through all the ones I know, but none seem to pay attention to partial content. I'm trying to retrieve a URL that gives the following header: HTTP/1.1 206 Partial Content Content-Range: bytes 0-100000/631723 As you can see it dishes out the file in 100,000 byte chunks. Trouble is, when I use any method in PHP, ie file_get_contents, fopen, or even cURL, none of these continue on after retrieving the 100,000 bytes. End result, I have a 100,000 byte file. What I need is to get the PHP script to grab all the data, in the example above, all 631,723 bytes. How can I do this? i am trying to retrieve messages with some code. It seems to be a bit more complicated that i thought it would be. so here it goes: Code: [Select] $query = "SELECT * FROM memberMail WHERE userIDFrom='92' AND unread='1'"; $result = mysql_query($query) or die(mysql_error()); if (mysql_num_rows($result) > 0) { $row = mysql_fetch_array($result) or die(mysql_error()); $num_rows = mysql_num_rows($result); echo "You have (" . $num_rows . ") unread message(s)."; $i = 0; for($i; $i<$num_rows; ++$i) { if($row[$i[unread]] == "1") { echo $row[$i[message]] . "<p>"; } } } what i am trying to do, is print out the messages from the records that are unread, and are from a certain user. i don't think this for statement will pick up the record numbers that got matches though. and i am not entirely sure about the $row statements in the for statement either.

I'm sending the textbox values via http request. Sending an element value via http request is usually be done using document.getElementById, assigning the elements ID to a var and posting the var name . Then accessing the value using $_POST. However I'm sending an array of string values. How do I access the array using $_POST? Any help appreciated. Hi Everyone! Just learning php. Hope someone can help with this.

I was working on a basic form on a multilanguage website so i need it to properly acknowledge what language it is working with. the link to the page would be like so: index.php?lang=en&sb=1 so the code, as required to read it, is as follows: Code: [Select] if(isset($_GET['lang']) == TRUE){ switch($_GET['lang']){ case 'en': case 'it': case 'pl': $validlang = $_GET['lang']; break; default: $validlang = 'en'; break; } } else{ $validlang = 0; } if(isset($_GET['sb']) == TRUE){ if(is_numeric($_GET['sb'] == FALSE)){ $error = 1; } if($error == 1){ header("Location" . $config_basedir); } else{ $validentry = $_GET['sb']; } } if($validlang == 0){ echo "An unknown error has occurred." . mysql_error(); } for whatever reason $validlang always comes out with the value 0. I even set tried setting $validlang = 'en'; before that snippet to at least force it to hold some value but I'm obviously doing something stupid here (isn't that usually the case ) that I can't seem to catch. Can anyone help clear this up for me? I really appreciate it! Hello, I am having a problem with retrieving information from my database.

Thank you very much! Hello all, I'm currently working on a project and it is the first time I have had to store/retrieve an array with PHP and MySQL. Basically its a website that has a list of discounts/coupons on it. People can register and submit their discounts and such. I am storing an array for who is eligible for the discount, as well as which categories the discount falls under. I did some googling and there seems to be tons of thoughts on the best way to do this. Some say to use implode/explode, some say to serialize/unserialize, I was just wondering if there is a common, concrete way to do this? I will need to be able to search the array for its contents. So if children are eligible for the discount, I need to be able to store that in a database, retrieve it later, and search it for only "Children" so I can display the discounts available only to children. If someone could please advise the best way to do this and post some examples, it would be greatly appreciated. I learn best with examples that are explained properly. |
