I have form that does a calculation, inserts in the bank and returns the value through a alert .
I would like to replace this message with alert with a modal .
HTML
<form method="post" action="#">
<input type="hidden" name="acao" id="acao" value="cadastrar"/>
<input type="text" name="alt" id="altura" required><br><br>
<input type="text" name="peso" id="peso" required><br><br>
PHP
function calcularIMC($altura,$peso){
$imc = 0;
if($altura >0 && $peso >0){
$imc = $peso / ($altura * $altura);
}
echo '<script>';
echo 'alert("'.$imc.'");';
echo '</script>';
}
I tried to do this:
- I added the code php after the </html> tag;
- I added the variable responsible for the calculation: $imc ;
- Linke the Enviar button with modal .
<form method="post" action="#">
<input type="hidden" name="acao" id="acao" value="cadastrar"/>
<input type="text" name="alt" id="altura" required><br><br>
<input type="text" name="peso" id="peso" required><br><br>
<button type="submit" id="Enviar" data-toggle="modal" data-target="#myModal">Enviar</button>
</form>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">
<?php echo'.$imc.';?>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</body>
</html>
PHP
<?php
function calcularIMC($altura,$peso){
$imc = 0;
if($altura >0 && $peso >0){
$imc = $peso / ($altura * $altura);
}
return $imc;
}
?>
With this, when I click the Enviar (with all empty fields) button, it opens the modal and displays the '.$imc.' as String.
When I enter the data and click on the Enviar button the window becomes opaque (start of the modal effect) and quickly returns to normal. I believe that modal is being called, but in some places it buga and date.
How can I resolve this?
