I have the following code:
// choices array
$choices = [];
$choices[1] = $_POST['choice1'];
$choices[2] = $_POST['choice2'];
$choices[3] = $_POST['choice3'];
$titlu = [];
$titlu[1] = $_POST['titlu1'];
$titlu[2] = $_POST['titlu2'];
$titlu[3] = $_POST['titlu3'];
if($insert_row){
foreach(array_combine($choices, $titlu) as $choice => $titlu)
{
if($choice != ''){
if($correct_choice == $choice) {
$is_correct = 1;
} else {
$is_correct = 0;
}
$query = "INSERT INTO `choices`(question_number, is_correct, choice, titlu)VALUES('$question_number', '$is_correct', '$choice', '$titlu')";
$insert_row = $mysqli->query($query) or die($mysqli->error.__LINE__);
if($insert_row) {
continue;
} else {
die('Error : ('.$mysqli->errno.') ' . $mysqli->error);
}
}
}
$msg = "Questions has been added";
}
}
My database tables are:
"Choices" which contain:
---------------------------------------------------
id | question_number | is_correct | choice | titlu |
---------------------------------------------------
My old code was without "titlu" row, i added it, and i used "aray_combine" for that .
Everything is working fine, rows are filled with info, but "is_correct" row don't work anymore. It show only "0" on all rows, even i select to show "1" .
Hope you understand me! I'm begginer, but i'm ready to learn.
Thank you!

Answer 1

I am not sure where are you getting your correct_choice value from.. but i did a quick test and it's working as expected.
$choices = [];
$choices[1] = 'bar';
$choices[2] = 'foo';
$choices[3] = 'elo';
$correct_choice = 'foo'; //added
$titlu = [];
$titlu[1] = 'llo';
$titlu[2] ='plo';
$titlu[3] = 'clo';
foreach(array_combine($choices, $titlu) as $choice => $titlu)
{
if($choice != ''){
if($correct_choice == $choice) {
$is_correct = 1;
} else {
$is_correct = 0;
}
$query = "INSERT INTO `choices`(question_number, is_correct, choice, titlu)VALUES('1', '$is_correct', '$choice', '$titlu')";
echo $query . "<br/>";
}
}
$msg = "Questions has been added";
output is
INSERT INTO `choices`(question_number, is_correct, choice, titlu)VALUES('1', '0', 'bar', 'llo')
INSERT INTO `choices`(question_number, is_correct, choice, titlu)VALUES('1', '1', 'foo', 'plo')
INSERT INTO `choices`(question_number, is_correct, choice, titlu)VALUES('1', '0', 'elo', 'clo')
may be there is something wrong with the way your correct_choice

Answer 2

Here is my HTML form:
<form method="post" action="add.php">
<p>
<label>Question Number</label>
<input type="number" value="<?php echo $next; ?>" name="question_number" />
</p>
<p>
<label>Question</label>
<input type="text" name="question_text" />
</p>
<p>
<label>Choice #1: </label>
<input type="text" name="choice1" />
</p>
<p>
<label>Choice #2: </label>
<input type="text" name="choice2" />
</p>
<p>
<label>Choice #3: </label>
<input type="text" name="choice3" />
</p>
<p>
<label>TITLU #1: </label>
<input type="text" name="titlu1" />
</p>
<p>
<label>TITLU #2: </label>
<input type="text" name="titlu2" />
</p>
<p>
<label>TITLU #3: </label>
<input type="text" name="titlu3" />
</p>
<p>
<label>Correct choice number </label>
<input type="number" name="correct_choice" />
</p>
<p>
<input type="submit" name="submit" value="Submit" />
</p>
</form>
I think here is my problem:
if($choice != ''){
if($correct_choice == $choice) {
$is_correct = 1;
} else {
$is_correct = 0;
}
Before to add "titlu" row and his values, there was filled with "$value", but i changed with "$choice"
