I have a problem, i searched for the solution all over the internet, but i couldn't find it out :S
The problem is:
I'm creating file inputs on button click, but i can't handle these javascript made inputs because they aren't in my $_FILES array after i click on submit..
My code is:
HTML:
<form name = "galleryupload_form" method = "post" action = "#" enctype="multipart/form-data">
<ul id = "formul">
</ul>
<input type="button" value="Még egy kép feltöltése" onClick="addInput('formul');">
<input name = "galleryupload_submit" type = "submit" value = "Küldés"/>
</form>
javascript:
var counter = 0;
var limit = 5;
function addInput(ulName) {
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
} else {
var newli = document.createElement('div');
newli.innerHTML = "<label for = ''>Fájl " + (counter + 1) + "</label><input type='file' name='files[]'>";
document.getElementById(ulName).appendChild(newli);
counter++;
}
}
If you now the solution, please let me know. Thank you.
Referring to the question before editing:
File inputs appear in $_FILES not $_POST.
After editing, I cannot reproduce the problem.
check this code .
<?php
if(isset($_POST['galleryupload_submit'])){
print_r($_FILES);
}
?>
<form name = "galleryupload_form" method = "post" action = "" enctype="multipart/form-data">
<ul id = "formul">
</ul>
<input type="button" value="My textbox goes" onClick="addInput('formul');">
<input name ="galleryupload_submit" type ="submit" value ="Click Add"/>
</form>
<script>
var counter = 0;
var limit = 5;
function addInput(ulName){
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
}else {
var newli = document.createElement('div');
newli.innerHTML = "<label for = ''>New TexBOx " + (counter + 1) +"</label><input type='file' name='files[]'>";
document.getElementById(ulName).appendChild(newli);
counter++;
}
}
</script>

I'm having a problem I'm using a numeric keypad that I found in codepen this one
https://codepen.io/matthewfortier/pen/ENJjqR
my objective is to store the generated pin in a database but it's a little difficult to do that because I'm taking the generated pin to an input but it looks like this
<input hidden="" id="pin" value="" name="pin">9345</input>
how do i get this generated pin and save it in database
the code is the same as the link
In your html you have this:
<input type="hidden" id="pin" value="9345" name="pin" />
In your Javascript you have this:
let value = document.getElementById('pin').value;
console.log(value);
$(function() {
var container = $(".numpad");
var inputCount = 6;
// Generate the input boxes
// Generates the input container
container.append("<div class='inputBoxes' id='in'></div>");
var inputBoxes = $(".inputBoxes");
inputBoxes.append("<form class='led' class='form-group' action='cadastro.php' method='post'></form>");
var led = $(".led");
// Generates the boxes
for(var i = 1; i < inputCount + 1; i++){
led.append("<input type='password' maxlength=1 class='inp' id='" + i + "' />");
}
led.append("<input type='password' maxlength=12 name='numero' value='93445566' id='numero' />");
led.append("<input type='text' name='te' id='te' placeholder='' />");
led.append("<button id='btn1' type='submit' onclick=''>enviar</button>");
container.append("<div class='numbers' id='inb'><p id='textoo'><span class='bolded'>PIN</span> do serviço MULTICAIXA</p></div>")
var numbers = $(".numbers");
// Generate the numbers
for(var i = 1; i <= 9; i++){
numbers.append("<button class='number' type='button' name='" + i + "' onclick='addNumber(this)'><span class='pin_font'>" + i + "</span></button>");
}
addNumber = function take(field,vall) {
if (!$("#1").val())
{
$("#1").val(field.name).addClass("dot");
}
else if (!$("#2").val())
{
$("#2").val(field.name).addClass("dot");
}
else if (!$("#3").val())
{
$("#3").val(field.name).addClass("dot");
}
else if (!$("#4").val())
{
$("#4").val(field.name).addClass("dot");
}
else if (!$("#5").val())
{
$("#5").val(field.name).addClass("dot");
}
else if (!$("#6").val())
{
$("#6").val(field.name).addClass("dot");
vall = $("#1").val() + $("#2").val() + $("#3").val() + $("#4").val()+ $("#5").val()+ $("#6").val();
document.getElementById("pini").innerHTML = vall;
}
}
I am using the following code to generate a user-defined number of text inputs via a loop.
The generated inputs vanish after being generated in the loop - I am not sure why? I suspect I am missing something very simple?
The next step for the program will be to take the user input from the generated text inputs and put them into an array of arrays if that's in any way relevant?
function Player_Entry(){
Loop_End = document.getElementById('Select_Number_Of_Players').value;
for (Loop_Count = 0; Loop_Count < Loop_End; Loop_Count++) {
Variable_Name = "Player_Name_" + Loop_Count + 1
Variable_Number = "Player_Number_" + Loop_Count + 1
console.log("Created, Variable Number: " + Variable_Name);
console.log("Created, Variable Name: " + Variable_Number);
var Variable_Name = document.createElement("input");
Variable_Name.type = "text";
Variable_Name.value = "";
document.getElementById('Generated_Form').appendChild(Variable_Name);
}
}
<form onsubmit="Player_Entry()">
<label for="Number_Of_Players">Number of players</label>
<input type="number" id="Select_Number_Of_Players" value="1" name="Number_Of_Players" min=1 max =12><input type ="submit">
</form>
<br>Enter Player Names<br>
<form id="Generated_Form"></form>
Any help, particularly pointing out obvious rookie errors, gratefully recieved.
It's because the input's type is set to submit, which causes the form to be submitted when it is clicked.
You can stop the form from submitting by adding return false in the onsubmit handler:
function Player_Entry() {
Loop_End = document.getElementById('Select_Number_Of_Players').value;
for (Loop_Count = 0; Loop_Count < Loop_End; Loop_Count++) {
Variable_Name = "Player_Name_" + Loop_Count + 1
Variable_Number = "Player_Number_" + Loop_Count + 1
console.log("Created, Variable Number: " + Variable_Name);
console.log("Created, Variable Name: " + Variable_Number);
var Variable_Name = document.createElement("input");
Variable_Name.type = "text";
Variable_Name.value = "";
document.getElementById('Generated_Form').appendChild(Variable_Name);
}
}
<form onsubmit="Player_Entry(); return false">
<label for="Number_Of_Players">Number of players</label>
<input type="number" id="Select_Number_Of_Players" value="1" name="Number_Of_Players" min=1 max=12/> <input type="submit" />
</form>
<br>Enter Player Names<br>
<form id="Generated_Form"></form>
either change the submit button to a button or preventDefault() to stop the submission of the form
function Player_Entry(){
event.preventDefault();
Loop_End = document.getElementById('Select_Number_Of_Players').value;
for (Loop_Count = 0; Loop_Count < Loop_End; Loop_Count++) {
Variable_Name = "Player_Name_" + Loop_Count + 1
Variable_Number = "Player_Number_" + Loop_Count + 1
console.log("Created, Variable Number: " + Variable_Name);
console.log("Created, Variable Name: " + Variable_Number);
var Variable_Name = document.createElement("input");
Variable_Name.type = "text";
Variable_Name.value = "";
document.getElementById('Generated_Form').appendChild(Variable_Name);
}
}
<form onsubmit="Player_Entry()">
<label for="Number_Of_Players">Number of players</label>
<input type="number" id="Select_Number_Of_Players" value="1" name="Number_Of_Players" min=1 max =12><input type ="submit">
</form>
<br>Enter Player Names<br>
<form id="Generated_Form"></form>
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>
<html>
<body>
<button onclick="createNewFiled()" id="incrementBtn" type="button">Click here</button>
<form id="form" action="">
</form>
</body>
</html>
<script type="text/javascript">
var counter = 0;
var incrementBtn = document.getElementById('incrementBtn');
var form = document.getElementById('form');
var createNewFiled = function() {
counter++;
var input = document.createElement("input");
var br = document.createElement("br"); // If you need new line after each input field
input.id = 'input-' + counter;
input.classList.add("inputClass");
input.type = 'text';
input.name = 'name'+counter;
input.placeholder = 'Input field ' + counter;
form.appendChild(input);
form.appendChild(br); // If you need new line after each input field
};
</script>
So I Have Looked Through The Site Only To Not Find The Answer For My Particular Problem. I Am Pretty New To Writing Code And Am Trying To Figure Out How To Remove A Form Field After Its Been Added with Javascript. Here is the code. I would Greatly Appreciate Feedback/Solutions.
var counter = 1;
var limit = 1000;
function addInput(Favorites){
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
}
else {
var newdiv = document.createElement('div');
newdiv.innerHTML = "<br>Favorite " + (counter + 1) + "<input type='text' name='Favorites[]'><input type ='button' value ='Remove'>";
document.getElementById(Favorites).appendChild(newdiv);
counter++;
}
function removeInput(newdiv){
document.getElementById('Favorites').removeChild(newdiv);
counter - 1;
}
}
<form>
<div id="Favorites">
Favorite 1<input type="text" name="Favorites[]">
</div>
<input type="button" value="Add New Favorite" onClick="addInput('Favorites');">
<input type = "button" value = "Save Changes">
</form>
there are various issues in your code so I have modified it a bit. So use following js code
var counter = 1;
var limit = 1000;
function addInput(){
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
}
else {
var newdiv = document.createElement('div');
newdiv.innerHTML = " <div class='inputElement'>Favorite " + (counter + 1) + "<input type='text' name='Favorites[]'><input type ='button' value ='Remove' onClick='removeInput(this)'></div>";
document.getElementById("Favorites").appendChild(newdiv);
counter++;
}
}
function removeInput(removeLink){
var inputElement = removeLink.parentNode;
inputElement.remove();
counter= counter - 1;
}
In html you can modify your code a bit
<form>
<div id="Favorites">
<div class='inputElement'>
Favorite 1<input type="text" name="Favorites[]">
</div>
</div>
<input type="button" value="Add New Favorite" onClick="addInput();">
<input type = "button" value = "Save Changes">
</form>
Check out above code here

If you have any issues with it . Let me know.
Maybe this help? Check the link here link
var counter = 1;
var limit = 2;
function addInput(Favorites) {
if (counter == limit) {
removeInput();
alert("You have reached the limit of adding " + counter + " inputs");
} else {
var newdiv = document.createElement('div');
newdiv.innerHTML = "<br>Favorite " + (counter + 1) + "<input type='text' name='Favorites[]'><input type ='button' value ='Remove'>";
document.getElementById(Favorites).appendChild(newdiv);
counter++;
}
function removeInput() {
var x = document.querySelector('#Favorites div:last-child');
x.remove();
--counter;
}
}
Got the following JS code:
<script language="javascript">
fields = 0;
pNR = 0;
err = 0;
function addInput() {
if (fields != 40) {
document.getElementById('text').innerHTML += "<input type='text' name='first" + pNR + "' value='' /><input type='text' name='second" + pNR + "' value='' /><br />";
fields += 1;
pNR += 1;
} else {
if (err == 0) {
document.getElementById('text').innerHTML += "<br />Adaugati maxim 40 ingrediente.";
err = 1;
}
document.form.add.disabled = true;
}
}
</script>
and the following HTML:
<input name="name" style="color:#ffffff;" class="name required" type="button" onclick="addInput()" value="Add" />
<div id="text">
</div>
By default, there are no fields. When I press the Add button (fields are added two by two with different names), fill in the fields and click again the Add button, the filled fields are emptied. What did I do wrong?
You aren't simply adding new inputs.
You are:
converting the existing ones to HTML (the value attribute is unchanged, it will still have the default value, not the current value)
adding the HTML for the new inputs to it
generating new DOM elements from that HTML.
Don't use innerHTML. Use createElement, appendChild and friends.
This:
document.getElementById('text').innerHTML += "<input type='text' name='first" + pNR + "' value='' /><input type='text' name='second" + pNR + "' value='' /><br />";
Becomes this:
var firstInput = document.createElement("input");
var secondInput = document.createElement("input");
firstInput.type = secondInput.type = "text";
firstInput.name = "first" + pNR;
secondInput.name = "second" + pNR;
var text = document.getElementById("text");
text.appendChild(firstInput);
text.appendChild(secondInput);
text.appendChild(document.createElement("br"));
And, for the else case:
var text = document.getElementById("text");
text.appendChild(document.createElement("br"))
text.appendChild(document.createTextNode("Adaugati maxim 40 ingrediente."));
