Deleting and element by using a php id inside javascript

I'm trying to do it so when a user checks a checkbox it gets the Email to a text field and when the user unchecks it it deletes the text field, here's the code that I've tried to use that's not working.
The php code:
<?php
$execItems = $conn->query("SELECT Nome,EmailGeral,Enviado FROM escolas");
while($infoItems = $execItems->fetch_array()){
echo "
<tr>
<td>".$infoItems['Nome']."</td>
<td>".$infoItems['EmailGeral']."</td>
<td><input type=\"checkbox\" id=\"{$infoItems['EmailGeral']}\"".($infoItems['Enviado']?' checked':' ')." onclick=\"emailNextWithAddress(this, '".$infoItems['EmailGeral']."');\"/>
</tr>
";
}
?>
And the javascript:
<script>
function emailNextWithAddress(chk,address) {
if(chk.checked === true){
var nextEmail, inside_where;
nextEmail = document.createElement('input');
nextEmail.value = address;
nextEmail.type = 'text';
nextEmail.name = 'email[]';
nextEmail.className = 'insemail';
nextEmail.style.display = 'inline-block';
inside_where = document.getElementById('addEmail');
inside_where.appendChild(nextEmail);
return false;
} else {
var nextEmail, inside_where;
nextEmail.value = address;
nextEmail.className = 'delemail';
inside_where = document.getElementById(<?php echo $infoItems['EmailGeral'] ?>);
inside_where.parentElement.removeChild(nextEmail);
return false;
}
}
</script>

You could add an id as the last parameter, and using it on your function :
<td><input type=\"checkbox\" id=\"{$infoItems['EmailGeral']}\"".($infoItems['Enviado']?' checked':' ')." onclick=\"emailNextWithAddress(this, '".$infoItems['EmailGeral']."', this.id);\"/></td>
<script>
function emailNextWithAddress(chk,address,id) {
if(chk.checked === true){
var nextEmail, inside_where;
nextEmail = document.createElement('input');
nextEmail.value = address;
nextEmail.type = 'text';
nextEmail.name = 'email[]';
nextEmail.className = 'insemail';
nextEmail.style.display = 'inline-block';
inside_where = document.getElementById('addEmail');
inside_where.appendChild(nextEmail);
return false;
} else {
var nextEmail, inside_where;
nextEmail.value = address;
nextEmail.className = 'delemail';
inside_where = document.getElementById(id);
inside_where.parentElement.removeChild(nextEmail);
return false;
}
}
</script>

at least you're missing some quotes around that id
pick whether double/single vs single/double quotes:
document.getElementById("<?php echo $infoItems['EmailGeral'] ?>")
document.getElementById('<?php echo $infoItems["EmailGeral"] ?>')

The snippet of php/html was missing a closing </td> tag after the checkbox.
The javascript function could, I believe, be simplified a little like this. I made an assumption here in that the new input element should be appended to the current table row - I could not determine what the element with id addEmail was or where it was. The below should append a new text field in the same cell as the checkbox, populate with the email address when checked and remove when the checkbox is unchecked.
<?php
$execItems = $conn->query("SELECT Nome,EmailGeral,Enviado FROM escolas");
while($infoItems = $execItems->fetch_array()){
$name=$infoItems['Nome'];
$email=$infoItems['EmailGeral'];
$checked=$infoItems['Enviado'] ? 'checked' : '';
echo "
<tr>
<td>$name</td>
<td>$email</td>
<td><input type='checkbox' id='{$email}' {$checked} onclick='emailNextWithAddress( this );' /></td>
</tr>";
}
?>
<script>
function emailNextWithAddress( chk ) {
try{
if( chk.checked === true ){
var nextEmail;
nextEmail = document.createElement('input');
nextEmail.value = chk.id;
nextEmail.type = 'text';
nextEmail.name = 'email[]';
nextEmail.className = 'insemail';
nextEmail.style.display = 'inline-block';
chk.parentNode.appendChild( nextEmail );
} else {
chk.parentNode.removeChild( chk.parentNode.querySelector('input[ name="email[]" ]') );
}
return false;
}catch( err ){
console.info( err.message )
}
}
</script>

Keyup in Firefox

I am trying to detect a keypress using the jQuery keyup function, but it does not seem to work in Firefox. Though it does work in Chrome, Edge, IE and Opera.
$(".textfield").contents().keyup(function(evnt) {
document.getElementById("btn_save").style.opacity = "1";
saved = false;
});
".textfield" is an iframe with designmode = 'on' So I'm trying to detect a keyup within a editable iframe.
Here's my iframe, nothing special:
<iframe class="textfield" name="textfield" frameBorder="0"></iframe>

PHP for saving the note

}
if (isset($_POST["posttext"]) && !empty($_POST["posttext"])) {

$insert = "INSERT INTO content (text) VALUES ('$content')";
mysqli_query($connection, $insert);
$id = mysqli_insert_id($connection);
}
?>

you can use jquery ...
$(document).ready(function(){
$(".textfield").keyup(function() {
$("#btn_save").css("opacity", 1);
});
});

Okay, I fixed the problem. Apparently Firefox needs $(document).ready() to properly function for keypress events (haven't tested other events).
So your code should be:
$(document).ready(function(){
$(".textfield").contents().keyup(function(evnt) {
document.getElementById("btn_save").style.opacity = "1";
saved = false;
});
});
Instead of:
$(".textfield").contents().keyup(function(evnt) {
document.getElementById("btn_save").style.opacity = "1";
saved = false;
});
As I already said this is a problem that only occured in Firefox AFAIK.
This code works in Chrome, Firefox, Opera, Edge and Internet Explorer as of time of writing this answer.

I had a similar problem.
The mobile keyboards (in Firefox) don't emit keyup, keydown and keypress events.
So, I met the Text Composition events.
Something like this:
myInput = document.getElementById('myInput');
myInput.addEventListener('compositionupdate', (event) => {
setTimeout(() => {
applyFilter(event)
});
})
The setTimeOut was necessary to wait input value receipt the keyboard value before call my function.

Why does php code not recognize a database update?

I have some php and html code and a small bit of JavaScript. Its a like system. Click the like button or dislike button and when you exit/leave the page the JavaScript and ajax runs a php file to update the database with the changes.(+1 to likes or +1 to dislikes or -1 to dislikes etc.) There is one problem. I click like/dislike and then i leave/ refresh page and the likes have not changed in value. If i dont click anything, which means im not updating the database and i refresh/leave a second time the likes are updated on the screen to what they should be. The database gets updated when its suppose to, its the code that dosnt use the new value for whatever reason. Here's my code:

What is wrong with the code that makes it not update the amount of likes on the first refresh but does update on the second refresh?

The .js looks like this

On the process.php part i want to listen the option value from select
"<select name="kategorija" id="kategorija">"
on the process.php when i
<?php
$kategorija = $_POST['kategorija'];
echo echo $kategorija;
?>
i alwasy get a 0 value, so what i am doing wrong? The file[] processing is working fine, but can't get it to work with a addtional variable.

You don't need to echo echo $kategorija; It should be echo $kategorija; If this causes an issue, which it might, try var_dump($kategorija) to view the contents of the variable.
Also, you're including your js throughout the page, this should be refactored and included properly in the head. The php should not be in the form of the document, it should be contained outside and included like you are doing with '../db/baza.php'; Finally, look into using PDO to connect to your db.

Toggle to open/close tabbed navigation

I am very new to jQuery/Javascript and have been trying to have a tabbed navigation menu closed on page load then open if clicked by the user. So far I haven't had any joy with editing the following file

When the page loads I woul like to have the tabbed navigation menus closed but toggable to open by the user... Can anyone assist please?

From the admin panel, you can make any of your filters closed by default:-
Catalog > Improved Navigation > Filters
Select the relevant filter and set 'Collapsed' to 'Yes'.
