How do I separate the result of an sql query?
Question
So I have dynamically implemented text fields on my form using jQuery and then used it to insert in my database. Now I have been encountered with two problems, one being every time user posts the form entries, I have all the entries inside on row separated by comma. And secondly, when I retrieve the same from database, I get the row as a whole. What I want is every word individually in a separate div. Here is the code for both:
form.php
<?php
include "init.php";
?>
<!DOCTYPE html>
<html>
<head>
<!--Import Google Icon Font-->
<link href="http://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<link type="text/css" rel="stylesheet" href="css/materialize.min.css" media="screen,projection"/>
<link type="text/css" rel="stylesheet" href="css/animation.css">
<!--Let browser know website is optimized for mobile-->
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
</head>
<body>
<form action ="result.php" method="post">
<div class="row">
<div class="input-field col s4 green-text text-lighten-3">
<input name="set_name" type="text" class="validate">
<label for="set_name">Set Name</label>
</div>
</div>
<div class="details">
</div>
<br>
<br>
<br>
<button class="btn waves-effect waves-light orange darken-4 text" type="submit" id="" name="action">Save
</button>
<div class="right bottom">
<a class="btn-floating btn-large waves-effect waves-light pink add_field_button"><i class="material-icons">add</i></a>
</div>
</form>
<!--Import jQuery before materialize.js-->
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="js/materialize.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var max_fields = 10; //maximum input boxes allowed
var wrapper = $(".details"); //Fields wrapper
var add_button = $(".add_field_button"); //Add button ID
var x = 1; //initlal text box count
$(add_button).click(function(e){ //on add input button click
e.preventDefault();
if(x < max_fields){ //max input box allowed
x++; //text box increment
$(wrapper).append('<div class="row"><div class="input-field col s6 green-text text-lighten-3"><input name="word[]" type="text" class="validate"><label for="word[]">Word</label></div><div class="input-field col s6 green-text text-lighten-3"><input name="def[]" type="text" class="validate"><label for="def">Definition</label></div><a class="btn waves-effect waves-light blue-grey darken-4 remove_field"><i class="material-icons">delete</i></a> </div>'); //add input box
}
});
$(wrapper).on("click",".remove_field", function(e){ //user click on remove text
e.preventDefault(); $(this).parent('div').remove(); x--;
})
});
</script>
</body>
And here is the result.php
<?php
include "init.php";
$name = $_POST["set_name"];
if($_POST){
$word = implode(",", $_POST["word"]);
$def = implode(",", $_POST["def"]);
echo $word;
echo "<br>";
echo $def;
}
$sql_query = "insert into table values('$name', '$word', '$def');";
if(mysqli_query($conn, $sql_query)) {
echo '<script language="javascript">';
echo 'alert("Inserted!")';
echo '</script>';
}
else {
echo '<script language="javascript">';
echo 'alert("Error in database, cannot insert.")';
echo '</script>';
}
$result = mysqli_query($conn, "SELECT set_word FROM ayush95 WHERE set_name = 'Hindi';");
if($result->num_rows > 0){
echo $result->fetch_object()->set_word;
}
$conn->close();
?>

You can use the explode php function. Here is an example from PHP doc.
// Example 1
$pizza = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2

TheZozoOwner is partially correct; however, that code will still echo out all on one line.
If you want it echoed out on individual lines, try this...
$pieces = explode(",", $result->fetch_object()->set_word);
$count = count($pieces);
for($i=0; $i < $count; $i++) {
echo $pieces[$i].'<br>';
}
Happy Coding !
