PHP - Two Level Mapping!
Hi -
I've got a program to allow the user to upload a file and then select, for each column of an existing table, the column from the new source table to insert. However, what I need to do is do the insert using the actual names, but show the user a drop-down menu of the LABELS they've chosen for each of these real, target columns. Is there a "clean" or "tricky" way of doing this? The code to do the inserts works by just reading the translation table that has two columns -- source column fieldname and target column (in the existing table) fieldnames (both real fieldnames, of course). Here's what I've got: <form action="index.php" method="post"> <input type="hidden" id="unique" name="unique" value="<?php echo $unique_nm; ?>" /> <input type="hidden" id="savetotable" name="savetotable" value="1" /> <?php foreach($LabelList as $c_name){ ?> <div> <div style="float: left; width: 300px;"; > <?php echo $c_name; ?> </div> <div style="float: left; width: 400px;"> <select id="<?php echo $c_name; ?>" name="<?php echo $c_name; ?>"> <option value=""></option> <?php foreach($SourceColumns as $h_name){ ?> <option value="<?php echo trim($h_name); ?>"> <?php echo trim($h_name); ?> </option> <?php } ?> </select> </div> <div style="clear: both;"></div> </div> <?php } ?> <input type="submit" value="Save to Database" /> </form> So, while I could load the data into the targetfile pretty easily using the real target table column names, how can I present the user with a drop-down menu of LABELS, but insert the data into the REAL target fields? Here's the list of ACTUAL fields: $output = array(); $gather = 'select FieldName from MapTable where User = UserID' $this->call($gather); foreach($this->data as $row){ $ActualFields[] = $row['COLUMN_NAME']; } return $ActualFields; } Here's the list of LABELS (phony field names): $output = array(); $gather = 'select LabelName from MapTable where User = UserID' $this->call($gather); foreach($this->data as $row){ $LabelList[] = $row['COLUMN_NAME']; } return $LabelList; } The list of fields from the sourcefile the user is loading are all actual, real names ($SourceColumns) Similar TutorialsHi guys, I am making a simple program which fetches an array of variables on my table. Basically, I want to map the location of a unit which is plugged into a certain location. The layout consists of 40 locations. I'll be representing them using tables. Lets say I have a table with 1 row and 40 columns which portrays the 40 locations. Lets say, collectively all 40 locations are on Area 238. So each location is labeled 238-1 ... 238-40). In my database I have a field called portNumber which has a value of say 238-11. Now I want the code to check all those data entries with the portNumber LIKE 238, and highlight all rows which return a value. Those without value will remain white. Also the highlighted values should check is the field isHistory is set to 0 otherwise, it won't return the value. Here's the code I did so far: Code: [Select] <!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; charset=utf-8" /> <title>Location Mapper</title> </head> <body> <table width="800" border="1" align="center" cellpadding="0" cellspacing="0"> <tr> <th colspan="40" scope="col">SCMST 238</th> </tr> <tr> <?php $conn = mysql_connect("localhost", "root", "123456") or die(mysql_error()); mysql_select_db("orderstatus") or die(mysql_error()); $sql = mysql_query("SELECT * FROM superdome WHERE portNumber LIKE '%238%' AND isHistory='0' ORDER BY portNumber ASC") or die(mysql_error()); if(mysql_num_rows($sql) != 0) { echo " <td width=\"20\" height=\"30\" scope=\"row\"> </th> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> <td width=\"20\"> </td> "; } ?> </tr> </table> </body> </html> So if the query for mysql_num_rows return 0, nothing should be highlighted as shown in the pictu but if the query for mysql_num_rows return a value, all values in the array should be highlighted as shown: Location 5 and 40 are highlighted. Really need help on this one... Thanks! I am really struggling with the logic aspect of my application. I can't picture the structure and get it clear in my mind. As a result, I can't code anything because I'm second-guessing myself at every turn.
My application is pretty simple in reality. It's an application that keeps a record of all the different 'contracts'/'agreements' that my colleagues have signed. Some will have signed three or four depending on what systems they are working on.
The application will run a cron, daily, and send out an email to anyone who's contract/agreement is about to expire with an invite for them to renew it.
I have already built an application that has a login system and authentication (using Laravel). It was my first Laravel effort and I did it using a tutorial from YouTube. I figured I could use the one login from that to act as the administrator for this whole application. Once the administrator is in, they will be presented with a panel to do various things. This is the part I am stuck on. What do you all think of my "logic"?
Here are the basic routes (forgetting the auth stuff which is already done);
/contracts - to see a list of all the contact templates out there.
/contracts/{contract-id} - to view the specific contract template
/contracts/create - GET and POST to be able to add new contract templates for other systems
/people - view all my colleagues on one page
/people/{person-id} - view a specific colleague and all the contracts they have signed
/people/create - GET and POST for this too to be able to add new colleagues to the system
/people/{person-id}/create-new-contract - so this would add a record in to a third table which joins info from the people table and the contracts table to make a list of unique contract agreements for each person and their expiry date. GET and POST for this as well I suppose. Even as I'm writing this, I don't know if this will be needed because I might have an emailing class that might do this job better? Hence the writing of this post!
/agreements/renew/{renew-code} - This will create a new record in the table and amend the old one to show that the previous agreement has expired and that a new one for the next 365 days is in place.
As you can probably tell.. I am struggling a bit. Is there any advice you can give me to help me mentally map out my application before I start coding? I just want to get it right..
Hi All, I have a function that creates an array using a few sql quereys. I then use the array to output to html. I am wanting to add more data to the array to populate another column in the created table. I am unsure how to add $miqty to the array and then output it in the Qty On Order column. I feel like i need to add the [] to $menuItemsInCat[$mcatname][$miid] = $miname; section but i am not sure where in there it should be.

As always your help is very appreciated. Edited February 5, 2020 by Adamhumbugi need to know how i can check a users level in my login.php page it works i have
$sql = "SELECT * FROM $tbl_name WHERE username = '$username' AND password='$password'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
$row = mysql_fetch_assoc($result);
$user_level = $row['user_level'];
if($count == 1) {
$_SESSION['loggedIn'] = true;
session_write_close();
header("Location: index.php");
} else {
echo "The username or password you entered is incorrect!";
} if($row['user_level'] == 1) {
header("Location: admin.php");
} else if($row['user_level'] == -1) {
header("Location: banned.php");
}
but i need to know how to check it in another file because it is not working i am trying to add it to admin.php to check the users level & if they are not admin then echo you are not admin. <-- it says that although the user is an administrator it is saying they are not.
This is what i have in admin.php
<?php
require 'connect.php';
session_start();
$sql = "SELECT * FROM $tbl_name WHERE username = '$username' AND password='$password'";
$result = mysql_query($sql);
$row = mysql_fetch_assoc($result);
$user_level = $row['user_level'];
if(!isset($_SESSION['loggedIn'])) {
echo "You are not currently logged in and to view this page you must be logged in to have access. <a href='login.php'> You can login here </a>";
die();
} if($row['user_level'] == 1) {
//DO NOTHING
} else {
echo "Your not an administrator so you are denied access to this page.";
die();
}
?>

Hi everyone, I'm very new to PHP and have been following Kevin Yank's "How to build a db driven website using php & mysql" 3rd ed. and am working through Chapter 6, where a basic search page is created. What I would like to be able to do is, in the results, display not only the joketext (as done in the book), but also the author's name (which is located in a different table in the db), as well as the date it was submitted (in the same db as joketext), possibly a link to another site and extra info like the joke category. In general, I would like to be able to understand how to adjust the php code to add data related to the results of any given search. The information is already related through the database, how do I use it in the results of a search? I've used the same names of variables and tables as used in the book. Thank you in advance for any help you can offer! I really appreciate it. Below is the code for the part of the code I would like to change (highlighted parts) followed by the code for whole page (2 main sections "search" and "results". In the main code, the excerpt below is located a few lines from the bottom (in "results"): Note: the only variable currently displaying in the results in $joketext (also highlighted).

Thanks very much everyone John Hello. Basically I have created a form that you fill in and an email gets sent to your in box and you have an access_level of 1. Within this email there is one field. A validation_id. Now what im trying to do is when you click this link it opens the webpage and updates your access_level to 2. I have wrote my query and array and i can see exactly which bit is wrong. Its where i have validation_id= $validation_id") Now its not working and I can see the error. Problem is im too new at this to understand why its wrong and how to fix it can anyone help? Here is the rest of the code. Also could you please explain? I would really like to understand it before i move any further. p.s. I have already selected my database in the included file <? include('database_name'); session_start(); $validation_id =$_GET['validation_id']; $FullRec__query=sprintf("SELECT * FROM Members WHERE validation_id= $validation_id"); $FullRec = mysql_query($FullRec__query, $database name) or die(mysql_error()); $FullRecArray = mysql_fetch_array($FullRec); $UdateAccessQuery = sprintf("UPDATE Members SET access_level = '2' WHERE validation_id = $validation_id"); mysql_query($UdateAccessQuery, $database_name) or die(mysql_error()); ?> In javascript you can do multiple methods on the same line like: if(document.getElementById('myElement').className.match(/^[0-9]/)){/*Do something*/} in that we have getElementById() and match() on the same line, and it works the same as if you were to split them on multiple lines. Is it possible to do that with php?

I want to have a multi level dropdown selection tool come out of an array (not database; almost all of available codes on the internet are based on mysql databse). I have an array as each element has this format: "Country | City | ID". Using explode, I want to make a dropdown to choose the country, then choosing the cities of the chosen country.

Administrator can perform all application tasks and Staff can ONLY perform certain task. I have implemented sessions quite alright and are working. Now the problem is that when I login as Staff and then I change the URL to point to an administrator's page the application is allowing that, How can I prevent that from happening. Staff MUST NOT see administrators pages. Here is my login code, logout code and code am using to protect webpages below. Here is my login code <?php //start the session session_start(); $username=$_POST['username']; $password=$_POST['password']; $encrypted=md5($password); // set connection to database $hostname="localhost"; // Host name $mysql_server_username="root"; // Mysql username $server_password=""; // Mysql password $db_name="db_inventory"; // Database name $table = "tbl_users"; // Table name // Connect to server and select database. mysql_connect("$hostname", "$mysql_server_username", "$server_password")or die("cannot connect to database server"); mysql_select_db("$db_name") or die ("Couldn't select the database."); $admin=("select * from $table where username='$username' AND password='$encrypted' AND type = 'admin'"); $staff=("select * from $table where username='$username' AND password='$encrypted' AND type = 'staff'"); //check that at least one row was returned $adminresult=mysql_query($admin); $admincount = mysql_num_rows($adminresult); $staffresult=mysql_query($staff); $staffcount = mysql_num_rows($staffresult); if($admincount> 0){ $_SESSION['valid_user'] = $username ; header( "Location: main_menu.php" ); } else if($staffcount> 0){ $_SESSION['valid_user'] = $username ; header( "Location: staff/main_menu.php" ); } else { ?> <!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; charset=utf-8" /> <title>title> | Login</title> </head> <body bgcolor="#FFFFFF" background-repeat:no-repeat; background="images/images1.jpg"> <div align="center"> <table width="800" height="501" border="0" cellpadding="1" cellspacing="1"> <tr> <td height="100"> </td> </tr> <tr> <td height="350"> <div align="center"> <form method="post" action="login_process.php"> <h4 align="center"><font color="red">Incorrect Username / Password !
