Olá Galera,

Estou tentando adaptar em meu sistema de noticias, um editor html para lançar os conteúdos das notícias de forma mais agradável. O problema que estou tendo é que este editor é em javascript e não imagino como pegar o valor php para cadastrar no banco de dados.

Veja o codigo:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<HTML>
    <HEAD>
                <TITLE>Test</TITLE>
        <script src="wsCTextEditor.js" type="text/javascript"></script>
    </HEAD>

<script language="JavaScript" type="text/javascript">
var editor = new wsCTextEditor('textEditor', '', "100%", 300, true, false);




</SCRIPT>

<BODY>
<?php

if(!isset($envia)){
?>
<form action="" method="POST">
    <script>
        editor.show();
    </script>
    <input type="hidden" value="editor.setHTML(this.value);" name="texto" id="texto" />
    <input name="envia" type="submit" value="Submit" >
</form>
<?php
}else{
echo $_POST[texto];

}
?>
</BODY>
</HTML>

Porém não consigo receber o valor via php.

alguém saberia como fazer isso?

Ou teria algum outro script para um editor html?

Obrigado!

Aguardo!

Acabei de jogar o nome no google e apareceu 6 resultados, provavelmente você digitou errado, de qualquer maneira, troque:

echo $_POST[texto];

Por

print_r($_POST);

Isso vai fazer com que tudo que for enviado por $_POST seja exibido, ai é só você ver o nome do índice do array...

Olá ESerra,

Bem não sei se você saca de javascript, pois tenho a impressão que para eu obter esse valor do Editor HTML terei de fazer um comando javascript.

Segue código javascript que é importado na página que uso o editor html:

function wsCTextEditor(name, html, width, height, buttons, readonly)
{
        this.name = name;
    this.html = html;
    this.width = width;
    this.height = height;
    this.buttons = buttons;
    this.readonly = readonly;
    
    this.setHTML = wsCTextEditorSetHTML;
    this.addHTML = wsCTextEditorAddHTML;
    this.show = wsCTextEditorShow;
    this.getHTML = wsCTExtEditorGetHTML;
    this.clear =wsCTextEditorClear;
    
    // Private
    this.updateHTML =wsCTextEditorUpdateHTML;
    


    initRTE("images/", "", "");
}


function wsCTextEditorSetHTML(html)
{
    this.html = html;
    this.updateHTML();
    
}

function wsCTextEditorUpdateHTML()
{
    if (document.all)
    {
        frames[this.name].document.body.innerHTML = this.html;
    }
    else
    {
        document.getElementById(this.name).contentWindow.document.body.innerHTML = this.html;
    }

}


function wsCTextEditorAddHTML(html)
{
    this.html += html;
    this.updateHTML();
}


function wsCTextEditorShow()
{
    writeRichText(this.name, this.html, this.width, this.height, this.buttons, this.readonly);
}


function wsCTExtEditorGetHTML()
{
       if (document.all)
    {
        return frames[this.name].document.body.innerHTML;
    }
    else
    {
        return document.getElementById(this.name).contentWindow.document.body.innerHTML;
    }
}


function wsCTextEditorClear()
{
    this.setHTML("");
}
