Eval error

Well, with only this:

<form action="" method="POST" style="padding-top:0px">
<table border="1" bordercolor="#000000" style="max-width:500px;">
<tr>
<td width="20%" bgcolor="#dddddd"><span class="Stile1"><b>Come calcolare le Proporzioni del Presepe?</b><br/>
  </span>
  <p class="Stile1">Inserire nella casella &quot;Dimensione real&quot; la misura espressa in cm di ci&ograve; che volete realizzare. Esempio per un muro di 1 metro dovremo inserire 100 cm</p>
  <div align="center"><b><span class="Stile1">1. Dimensione real:</span>&nbsp;</b><input type="text" name="real" size="10" value=""></div><br/><br/>
<p class="Stile1">Inserire l'height della statuetta espressa sempre in cm</p><div align="center"><span class="Stile1"><b>2. Altezza Statua:</b></span><b>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</b><input type="text"name="height" size="10" value=""></div><br/><br/>
<div align="center"><b>3.</b>&nbsp;<input type="submit" value="Ottieni Proporzione"></div></td>
</tr>
<tr>
<td bgcolor="#33CCFF"><p class="Stile1">Il risultato ottenuto nella casella &quot;proporzione&quot; &egrave; la misura del muretto in proporzione alla statuetta</p>
  <div align="center"><span class="Stile1"><b>Risultato della Proporzione:</b></span><b>&nbsp;</b>
    <input type="text" name="total" size="10" value=""></div></td>
</tr>
<tr>
<td height="61" bgcolor="#dddddd"><span class="Stile1">L'height &egrave; stata impostata come default a 170 cm height media dell'uomo.</span></td>
</tr>
</table>
</form>

This code is just HTML, and if I have the “PHP Code” marked at the plugin option, still the same error.
If I remove the PHP Code mark, then this last html will appear. (But will not work as intended)

If I remove the php code mark and put the 1st code instead, then on the value space it will appear: <?php echo htmlspecialchars($real);?>

PS: This code worked in the past with php-code-for-posts plugin. If that matters.

I’ve thought of a workaround:

I created 2 snipets. One just for the 1st block content just php:

<?php
	if (isset($_POST['real'])){
		$real=$_POST['real']; //Get the global variable of the first number
		$height=$_POST['height']; //Get the global variable of the second number
		if ($real!=null or $height!=null){ //I continue if at least one number is defined
			if ($real==null){ $real=0; } //If the first number is null, I associate it with zero
			if ($height==null){ $height=0; } //If the second number is null, I associate it with zero
			$total=$real*$height/170; //High numbers and define $total (result)
			$total=round($total,2);
		}
	}
	else{
	$real=0;
	$height=0;
	$total=0;
	}
?>

And then I created another snippet for the HTML code (that still have some php inside):

<form action="<?php htmlspecialchars($_SERVER['PHP_SELF']); ?>" method="POST" style="padding-top:0px">
<table border="1" bordercolor="#000000" style="max-width:500px;">
<tr>
<td width="20%" bgcolor="#dddddd"><span class="Stile1"><b>Come calcolare le Proporzioni?</b><br/>
  </span>
  <p class="Stile1">Inserire nella casella &quot;Dimensione real&quot;</p>
  <div align="center"><b><span class="Stile1">1. Dimensione real:</span>&nbsp;</b><input type="text" name="real" size="10" value="<?php htmlspecialchars($real);?>"></div><br/><br/>
<p class="Stile1">Inserire l'height</p><div align="center"><span class="Stile1"><b>2. Altezza Statua:</b></span><b>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</b><input type="text"name="height" size="10" value="<?php htmlspecialchars($height);?>"></div><br/><br/>
<div align="center"><b>3.</b>&nbsp;<input type="submit" value="Proporzione"></div></td>
</tr>
<tr>
<td bgcolor="#33CCFF"><p class="Stile1">Il risultato ottenuto</p>
  <div align="center"><span class="Stile1"><b>Risultato Proporzione:</b></span><b>&nbsp;</b>
    <input type="text" name="total" size="10" value="<?php htmlspecialchars($total);?>"></div></td>
</tr>
<tr>
<td height="61" bgcolor="#dddddd"><span class="Stile1">L'height &egrave; stata impostata.</span></td>
</tr>
</table>
</form>

And I did do this change:

On the ShortCode.php I thought on changing the:
eval($content);
to
eval(‘ ?>’ . $content . ‘<?php ‘ );

And therefore since it has php code in both I’ve put the mark on the “PHP Code”.

It appears without error, but when I click submit it refresh the page but doesnt give the result. :/

I didn’t check the console yet.
