How to take out the anchor element from echo (functions.php) and place it to body (index.php)? PS: Newbie here guys, just trying to understand about HTML, CSS, Javascript and PHP a

Solution 1:

You forgot <li></li> in your code

You need to learn to return an array and to use foreach():

  <!doctype html>
  <?php include_once("functions/functions.php"); ?>
  <html>
  <head>
  <link rel="stylesheet" href="styles/style.css" type="text/css" />
  </head>
  <body>
<ul id="cats">
<?
     $cats = getCats();        
     foreach($cats as $cat){
        echo "<li><a href='index.php?cat=$cat[cat_id]'>$cat[cat_title]</a></li>";
     }    
?>
<ul>
</body>
</html>
    function getCats(){
    global $con;
    $get_cats = "select * from categories";
    $run_cats = mysqli_query($con, $get_cats);
    while ($row_cats=mysqli_fetch_array($run_cats)){
        $cats[]=$row_cats;
    }
  return $cats;
}

Solution 2:

I guess you can try something like this, if you really want to move the < a > elements to the body.However I think that the way you did it was better (there is no reason to move them to the body):

<!--index.php-->
<!doctype html>
<?php include_once("functions/functions.php"); ?>
<html>
<head>
<link rel="stylesheet" href="styles/style.css" type="text/css" />
</head>
<body>

    <ul id="cats">
      <?php 
        $get_cats = "select * from categories";
        $run_cats = mysqli_query($con, $get_cats);
        while ($row_cats=mysqli_fetch_array($run_cats))
        {
           $cat_id = $row_cats['cat_id'];
           $cat_title = $row_cats['cat_title'];
      ?>

    <a href='index.php?cat=<?php echo $cat_id;?>'><?php echo $cat_title;?></a>

    <?php
        }
    ?>
    </ul>

</body>

And in functions.php you just need to leave the mysql connection object:

$con = mysqli_connect("localhost","root","","justLearning");
if (mysqli_connect_errno())
{
   echo "The connection was not established: " . mysqli_connect_error();
}

Solution 3:

I'm guessing here but I reckon the problem is that the includes_path is set to the default and the included file isn't being found???

<?php 
    set_include_path( $_SERVER['DOCUMENT_ROOT'] . '/functions/' );
    include_once( "functions.php" );
?>

<!--index.php-->
<!doctype html>
    <html>
        <head>
        <title>There must be a title to be considered VALID html</title>
        <link rel="stylesheet" href="styles/style.css" type="text/css" />
    </head>
    <body>
        <ul id="cats">
          <?php 
            getCats();
          ?>
        </ul>
    </body>
</html>
