I'm using the
<button class="button button1" value="janeiro"
onclick="location.href=
'escolha_dia.php?inst=<?=$acao;?>&sala=<?=$acao2;?>&ano=<?=$acao3;?>&mes=janeiro';">
Janeiro</button>
but the result is double-quoted ":
http://localhost/teste/confirmar.php?inst=ufruralrj"&sala=ichs_paulo_freire"&ano=2016"&mes=janeiro"
How do I get this out?
I assume you came from this answer to another question from you:
In the original post (duly corrected by @rodorgas) quotes were missing in the value , and as a consequence, the end quotes became part of the value.
<input name="inst" value=<?=$acao;?>">
^-- aqui faltou abrir aspas
Try this:
<input name="inst" value="<?=$acao;?>">
In fact, the ideal even is this:
<input name="inst" value="<?php echo htmlentities( $acao );?>">
This ensures that special characters will be properly handled, avoiding conflict with HTML.
Apparently the values are already being double-quoted, which is strange. The ideal would be to investigate this, but if you just want to treat it the way it came, you can do it like this:
<?php
$acao = 'ufruralrj"';
$acao2 = 'ichs_paulo_freire"';
$acao3 = '2016"';
foreach ($$vars = array(&$acao, &$acao2, &$acao3) as &$var) {
$var = rtrim($var, '"');
}
echo ("
<button class=\"button button1\" value=\"janeiro\"
onclick=\"location.href=escolha_dia.php?inst=$acao&sala=$acao2&ano=$acao3&mes=janeiro\">
Janeiro
</button>
\n");
?>
