  1. How to get an array index by its value (key)? Is there a special function for that in PHP? For example, I have an array $a ["zero","one","two"] and a variable $b = "two", I know the value is in the array, but I don't know its index.
  2. Hi everyone. So I am have an issue to were I am trying to send information to my database and I get this error: NOTICE: Undefined index This is the code I am using: index.php <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Test Page</title> <link rel="stylesheet" type="text/css" href="style.css"> </head> <body> <form action="signup.php" methos="POST"> <input type="text" name="first" placeholder="First Name"><br> <input type="text" name="last" placeholder="Last Name"><br> <input type="text" name="uid" placeholder="Username"><br> <input type="password" name="pwd" placeholder="Password"><br> <button type="submit">SIGN UP</button> </form> </body> </html> signup.php <?php include 'dbh.php'; $first = $_POST['first']; $last = $_POST['last']; $uid = $_POST['uid']; $pwd = $_POST['pwd']; $sql = "INSERT INTO username (first, last, uid, pwd) VALUES ('$first', '$last', '$uid', '$pwd')"; $result = mysqli_query($conn, $sql); ?> dbh.php <?php $conn = mysqli_connect("localhost", "root", "", "logintest"); if (!$conn) { die("Connection failed: ".mysqli_connect_error()); } ?> So this is the code I am using. I know it is connecting to the database because the PRIMARY KEY is entering without an issue but the information is now being filled in. I.E. First name, Last name, User, and Password. If anyone can help me that would be great.
  3. Dear all, I am trying to dig into the exact difference between key and index in MySQL tables. Some say they are synonymous, others give some differences. I still don't feel confident enough to decide when to use each on a table. I would appreciate if someone well-versed in their difference explain such difference and when to use each. Thanks.
  4. I am creating a table using phpMyAdmin. I would appreciate if someone would explain: In the collation, I am selecting utf8_general_ci. Is this OK? For indexing, when should I use ''unique and when would I use 'index'?
  5. Hello, To start, sorry for my english i'm French ^^ I have a problem, in fact I can't retrieve the index of the row in a table. I tried many things but I haven't found the solution. Here is my code: <script id='TableSuser'> var oTableSuser = new sap.ui.table.Table({editable:false, width: "400px", visibleRowCount:2}); var oControl = new sap.ui.commons.Button({text : "{suser}", press : function() {openDialog(oTableSuser.getSelectedIndex());}}); oTableSuser.addColumn(new sap.ui.table.Column({label: new sap.ui.commons.Label({text: "Suser"}), template: oControl, sortProperty: "Button", filterProperty: "Button", name: "password_colonne"})); oControl = new sap.ui.commons.TextView({text:"{suser_mdp}"}); oTableSuser.addColumn(new sap.ui.table.Column({label: new sap.ui.commons.Label({text: "suser_mdp"}), template: oControl, sortProperty: "suser_mdp", filterProperty: "suser_mdp", visible: false})); var oModel = new sap.ui.model.json.JSONModel(); oModel.loadData("suser.php"); oTableSuser.setModel(oModel); oTableSuser.bindRows("/"); function openDialog(index) { var currentRowContext = oTableSuser.getContextByIndex(index); var valeur_suser_mdp = oModel.getProperty("suser_mdp",currentRowContext); alert(index); alert(currentRowContext); alert(valeur_suser_mdp); oTableSuser.getColumns()[1].setVisible(true); }; oTableSuser.placeAt("suser"); </script> I would like to retrieve the index of the row when I call the function function() {openDialog(oTableSuser.getSelectedIndex());} I tried different things and I didn't find how to retrieve the index of the row, I always have "-1" If someone has an idea I'm interested? Thx

  7. Hey guys, I have the following problem: On my blog (http://nachdenkblog.tumblr.com) I want to make it possible to switch directly between the blog entries.At the bottom of the main site you can see pagination between the sites. (BTW, it's in German but I guess you see what it means.) But if you open a specific entry you can see a similar but smaller footer without links to click.The code I used for this is the following: {block:PermalinkPage} <div class="FUSSBEREICH PERMA"> <div class="SCHATTEN"> </div> <div class="FUSS"> <div class="NAVIGATION"> {block:Pagination} <ul> {block:PreviousPost} <li> <a href="{PreviousPost}"> Vorheriger Eintrag </a> </li> {/block:PreviousPost} {block:NextPost} <li> <a href="{NextPost}"> Nächster Eintrag </a> </li> {/block:NextPost} </ul> {/block:Pagination} </div> </div> </div> {/block:PermalinkPage} (In case you need to know: FUSSBEREICH = footer; SCHATTEN = shadow; FUSS = foot)But as I said, no link at all is displayed. Can someone tell me why? Regards,Thomas
  8. I would like to do a script that includes content from pages according what the user chooses. Example If the users chooses Contact us from the menu I would like to have the index page displayed with the contact us content( www.website.com/index.php?page=contact-us ). I know it is done by GET requests but don't know how to do it or what is it called. Does anyone have a script or a tutorial on how to do it? Or at lest what is it called so I find a tutorial. Thanks before hand.
