Combobox in html and php - php

Question

If the combobox select the Archers the browser will echo Correct but if the combobox will not select the Archers the browser will echo, i want to know if my syntax is wrong.
Wrong. Error: Undefined index text_hname.
Here's the structure:
<form action="server.php" method="POST">
<img src="images/logo.png" class="logo">
<div class="container">
<h1>Account Details</h1>
<br>
<label class="username">Username</label>
<input type="text" name="text_username" class="text_user" placeholder="Enter username">
<label class="password">Password</label>
<input type="text" name="text_password" class="text_pass" placeholder="Enter password">
<label class="email">Email</label>
<input type="text" name="text_email" class="text_email" placeholder="Enter email">
<label class="cname">Character Name</label>
<input type="text" name="text_cname" class="text_cname" placeholder="Enter Character Name">
<label class="character">Select Character</label>
<select class="names" name="text_hname">
<option>Archer</option>
<option>Barbarian</option>
<option>Balloon</option>
<option>Witch</option>
<option>Spirit</option>
<option>Hog Rider</option>
<option>Minion</option>
</select>
<img src="images/">
<br>
<input type="submit" class="submit" name="submit">
</div>
</form>
//option
$hero = $_POST['text_hname'];
if (isset($_POST['text_hname'])) {
if ($hero == 'Archers') {
echo "Correct";
} else {
echo "wrong";
}
}

Answer 1

The problem is that if you're trying to assign $hero before you've checked if text_hname is set, it might not be defined.
Suggested refactor:
if (isset($_POST['text_hname'])) {
$hero = $_POST['text_hname'];
if ($hero == 'Archers') {
echo "Correct";
}
else
{
echo "wrong";
}
}

Answer 2

//Your select in form needs values. Same values that you are going to compare.
<select class="names" name="text_hname">
<option value="Archer">Archer</option>
<option value="Barbarian">Barbarian</option>
<option value="Balloon">Balloon</option>
<option value="Witch">Witch</option>
<option value="Spirit">Spirit</option>
<option value="HogRider">Hog Rider</option>
<option value="Minion">Minion</option>
</select>
//Php code
if (isset($_POST['text_hname'])) {
$hero = $_POST['text_hname'];
if ($hero == 'Archer') { //Its Archer, not Archers
echo "Correct";
}
else
{
echo "wrong";
}
}

Answer 3

$_POST['text_hname'] will return the selected option value , not option name .
Modify your select like this:
<select class="names" name="text_hname">
<option value="Archer">Archer</option>
<option value="Barbarian">Barbarian</option>
<option value="Balloon">Balloon</option>
<option value="Witch">Witch</option>
<option value="Spirit">Spirit</option>
<option value="Hog_Rider">Hog Rider</option>
<option value="Minion">Minion</option>
</select>
and server.php page
if (isset($_POST['text_hname'])) {
$hero = trim($_POST['text_hname']); //** to remove any whitespace
if ($hero == 'Archer') {
echo "Correct";
} else {
echo "wrong";
}
}
EDIT : it might be because your $_POST['text_hname'] has whitespace. Try trim() on $_POST['text_hname']
Hope it's helpful.
