I have a button that I generate with AJAX and on that same button it has an event onclick , and I want to pass two arguments to it, however I am having bugs with it.
PHP code:
echo ' <button type="button" class="btn btn-link btn-comentario-reposta" id="botao-esconde-resposta-'.$_POST['id'].'"
onclick="acao_botao_esconde_resposta('.$_POST['id'].','. $btn_mostrar_resposta .')">Esconder respostas</button>';
Here's what the Hide Answers button was for.
Your problem is that you failed to escape the '' of your arguments, correcting your code it looks like this:
echo ' <button type="button" class="btn btn-link btn-comentario-reposta" id="botao-esconde-resposta-'.$_POST['id'].'"
onclick="acao_botao_esconde_resposta(\''.$_POST['id'].'\',\''. $btn_mostrar_resposta .'\')">Esconder respostas</button>';
How it works:
In order to escape some special character such as "" the quotation marks or '' simple quotation marks that we use to pass arguments inside the functions we use the \ backslash so that in the code it considers the character as part of the string, an example which can be better explained is the following:
$id = $_POST['id'];
$email = $_POST['email'];
$html = '<button id="btn-'.$id.'" onclick="func_teste('.$id.','.$email.')"></button>';
echo $html;
This would be your case where the error happens and why? Well when this code is for the html it will be generated this way for example:
<!-- código html -->
<button id="btn-1" onclick="func_teste(1,[email protected])"></button>
<!-- código html -->
As we can see, the parameter path is wrong and so your code is printing )">Esconder respostas to avoid this problem you have to put the \"\" quotation marks or \'\' single quotes to make your escape and thus they become literal .
$id = $_POST['id'];
$email = $_POST['email'];
$html = '<button id="btn-'.$id.'" onclick="func_teste(\''.$id.'\',\''.$email.'\')"></button>';
echo $html;
And the result will look like this:
<!-- código html -->
<button id="btn-1" onclick="func_teste('1','[email protected]')"></button>
<!-- código html -->
Personally I think in your case it is simpler to write the html as html and put only what comes from php with <?=
<?php
$id = $_POST["id"];
?>
<button type="button" class="btn btn-link btn-comentario-reposta"
id="botao-esconde-resposta-<?=$id?>"
onclick="acao_botao_esconde_resposta('<?=id?>','<?=$btn_mostrar_resposta?>')">
Esconder respostas
</button>
