I want to create another input field, everytime the button " " inside the form is clicked. I searched for a solution but i can't find anything. The input field should be created inside the form over the " " button.
Here is my current code:
<div class="row">
<div class="col-md-12">
<form method="post" id="create-form" action="create.php" enctype="multipart/form-data">
<?php
/* getting sample questions */
/* checks result and creates variables from result */
if ($sampleamount > 0) { // amount
$samplequery->bind_result($questionid_sample, $question_sample);
while ($samplequery->fetch()) { // while page can use this variables
/* echo text-box, value from db */
$required = $questionid_sample === 1 ? "required" : ""; // one question is always required
echo "<input class='question-box' type='text' name='" . $questionid_sample . "' placeholder='Write your question in here.' maxlength='255' size='70' value='" . $question_sample . "'" . $required . "> <br>";
}
} else {
/* no result (db=sample_question) */
header('Location: ../index.php');
}
$samplequery->close();
closeDB($conn);
/* adds more input for user */
for ($i = ($sampleamount 1); $i <= ($additionalquestions $sampleamount); $i ) {
echo "<input class='question-box' type='text' name='" . $i . "' placeholder='Write your question in here.' maxlength='255' size='70'> <br>";
}
?>
<br>
<input class="createsurvey2" type="button" id="addqbtn" name="addqbtn" value=" " >
<br>
<input class="createsurvey2" type="submit" name="btnSubmit" value="Create Survey!" >
</form>
</div>
</div>
</div>
<script>
function addquestion() {
var counter = 2;
var addqbtn = document.getElementById('addqbtn');
var form = document.getElementById('create-form');
var addInput = function() {
counter ;
var input = document.createElement("input");
input.id = 'additionalquestion-' counter;
input.type = 'text';
input.class = 'question-box';
input.name = 'name';
input.placeholder = 'Write your question in here.';
form.appendChild(input);
};
addqbtn.addEventListener('click', function(){
addInput();
}.bind(this));
};
</script>
