I've written a while loop in PHP which creates many buttons which contain their individual username in a drop-down list, which relate to some usernames being brought in from a database. (it's a friend adding system)
I would like to be able to get the username from the clicked button and just store it in a variable, I know what to do from there, but I can't work that out.
if($getAddFriendUsernamesResult)
{
$row=mysqli_fetch_array($getAddFriendUsernamesResult);
while($row)
{
$username = $row['username'];
if($username!=$_SESSION['_username']) #Doesnt print the users own name in add friends
{
?><a><button class="AddFriendButton"><?php echo $row['username']; ?></button></a>
<?php
}
$row=mysqli_fetch_array($getAddFriendUsernamesResult);
}
}
At the moment this lists all of the usernames accept the person logged in in a long list. I want to get the contents of the button (the username of the clicked button) and store that in a php variable.
First, get rid of the <a>
tag.
Then give the button name
and value
attributes.
<button name="add_friend" class="AddFriendButton" value="<?= $row['username'] ?>">
<?= echo $row['username']; ?>
</button>
Then (assuming all the code in your loop is contained in a <form>
element), you'll be able to get the value from $_POST['add_friend']
.
Overall, something like this:
<?php if ($getAddFriendUsernamesResult) {
// open a form
echo '<form method="post" action="add_friend.php">';
while ($row = mysqli_fetch_array($getAddFriendUsernamesResult)) {
$username = $row['username'];
if ($username != $_SESSION['_username']) {
// give each button a name and value - may want to use id instead of username
echo "<button name='add_friend' value='$row[username]' class='AddFriendButton'>
$row['username']
</button>";
};
}
echo '</form>';
}
