How do I force a refresh on click on php? - php

Question

I have two buttons in html which are back and next.
If i click those buttons a variable gets incremented or decremented.
This variable is getting sent to a function.php where there is an sql statement.
The statement is:
select * from x where dimension is = value
How do I refresh the page to show my new table out of my query?
That is my php right here:
function tbl_showPage($page){
global $mysqlhost, $mysqluser, $mysqlpwd, $mysqldb;
$connection=mysqli_connect($mysqlhost, $mysqluser, $mysqlpwd) or die ("Verbindungsversuch fehlgeschlagen");
mysqli_select_db($connection, $mysqldb) or die("Konnte die Datenbank nicht waehlen.");
if($page<1)
{
$sql_tbl_questions = "SELECT * FROM `questions` where istAktiv='1' && dimension='1'";
}
elseif($page>9)
{
$sql_tbl_questions = "SELECT * FROM `questions` where istAktiv='1' && dimension='9'";
}
else
{
$sql_tbl_questions = "SELECT * FROM `questions` where istAktiv='1' && dimension=$page";
}
$quest_query = mysqli_query($connection, $sql_tbl_questions) or die("Anfrage nicht erfolgreich");
$i = 0;
while ($question = mysqli_fetch_array($quest_query)) {
$i++;
echo '<tr>';
echo '<th>'.$i.'</th>';
echo '<th>'.$question['question'].'</th>';
echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="0" required></th>';
echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="2.5"></th>';
echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="5"></th>';
echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="7.5"></th>';
echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="10"></th>';
echo '</tr>';
$dimensions = $question['dimension'];
}
echo '<tr>';
echo '<th></th>';
echo '<th>Kommentar/Ihre Anmerkung</th>';
echo '<th class="text-center" colspan=5><textarea rows=3 cols=50 name="Kommentar"></textarea></th>';
echo '</tr>';
echo '<input type="hidden" name="gesamt" value="'.$i.'">';
echo '<input type="hidden" name="dimensions" value="'.$dimensions.'">';
echo '<input type="hidden" name="size" value="'.$_POST['size'].'">';
echo '<input type="hidden" name="branche" value="'.$_POST['branche'].'">';
}
maybe my var is not beeing passed probably?
The javascript function is looking like that:
<script type="text/javascript">
var ki = kd = 1;
function increase()
{
ki++;
$.ajax({
type: "POST",
url: 'inc/functions.php',
data: ({page:ki}),
success: function(data){
console.log(data);
}
});
window.location.reload();
}
function decrease()
{
kd--;
$.ajax({
type: "POST",
url: 'inc/functions.php',
data: ({page:kd}),
success: function(data){
console.log(data);
}
});
window.location.reload();
}
</script>
I can't really figure out my problem, is my variable which I am generating in the function not passed properly, or is there another problem?

Answer 1

Seems as if you are mixing PHP and javascript here.
Do you have a onClick-function on your button? If you do, and a javascript function is called you can just add window.location.reload(); at the bottom of your javascript function to reload the page.
Tips: Use the edit function on your post and add code related to your problem, then it is easier to get help.

Answer 2

It is easy to make in JavaScript,
function myFunction() {
window.location.reload();
}
And then you just add the function to your button,
<button class="myButton" onclick=myFunction()">Click to reload</button>
