How do I identify with PHP if a submit button was clicked? and after the click I want to send a click confirmation message !. Detail everything in PHP. !!!
So it is not working not
<form method="POST">
<input type="text" name="salario"><br/><br/>
<input type="text" name="bonificacao"><br/><br/>
<input type="submit" name="btn">
</form>
<?php
$btn = $_POST['btn'];
if(!$btn){
echo " O botão foi clicado ";
}else{
}
if (isset($_POST['btn'])){
echo " O botão foi clicado ";
}else{
echo "esperando botão ser clicado";
}
You should use a medium that relates to POST to check if the button was clicked, see example:
<form action="" method="post">
<input type="text" name="salario"><br/>
<input type="text" name="bonificacao"><br/>
<input type="hidden" name="validar" value="989">
<input type="submit" name="go" value="Vai" />
</form>
<?php
if(isset($_POST['validar'])){
$valida = $_POST['validar'];
if($valida == 989){
echo 'Clicado';
}
}
?>
Try to take the exclamation out of your condition, you're denying the condition.
If it does not work, try this. Put value in submit :
<form method="POST">
<input type="text" name="salario"><br/><br/>
<input type="text" name="bonificacao"><br/><br/>
<input type="submit" name="btn" value="Botão">
</form>
Whenever you submit it will send the submit, hence you check if it is passing the value:
<?php
if (isset($_POST['btn']) and ($_POST['btn'] <> "")) {
echo " O botão foi clicado ";
} else { }
