I’m putting the contents of an iframe in an input, only it does not appear complete, just this in the input text:

<iframe width=

And it appears on the bottom line:

" type="text"/>

Look at the code where I update the field "name" and "iframe", when it appears what is registered in iframe is giving problem, iframe does not appear all in the input:

<?php include("header.php"); ?>
<div id="box">
    <div id="header">
        <div id="header_logo">
            <a href="painel.php"><img src="../images/DCDesenvolvimento.png" alt="" border="0"/></a>
        </div>
    </div>
    <div id="content">
        <div id="menu">
            <?php include("menu.php");?>
        </div>

        <div id="conteudo">
            <span class="caminho">Home &raquo; Editar Vídeos</span>
            <h1>Cadastrar Post</h1>
<?php
            if(isset($_POST['cadastrar_post']) && ($_POST['cadastrar_post'] == "cad"))
            {
                $id_a_editar = strip_tags(trim($_POST['id_do_post']));
                $nome = strip_tags(trim($_POST['nome']));
                $iframe = $_POST['iframe'];
                $editar_posts = mysqli_query($conexao,"UPDATE baterista 
                                                            SET nome = '$nome', video = '$iframe'
                                                                WHERE id = '$id_a_editar'")or die(mysqli_error($conexao));
                if($editar_posts>=1)
                {
                    echo "<div class=\"ok\">Seu tópico foi atualizado com sucesso!</div>";
                }
                else
                {

                }
            }

            $editar_post_id = $_POST['id_do_post'];

            $dados = mysqli_query($conexao, "SELECT id, nome, video 
                                                FROM baterista WHERE id = '$editar_post_id'")or die(mysqli_error($conexao));
            if(mysqli_num_rows($dados) == 0)
            {

Is giving conflict with the double quotes of the string $iframe, which is an HTML code that has attributes using double quotes, with double quotes from value="". This is causing a break in the delimiter (double quotes) of the attribute value of input.

Your code is getting something like this:

<input name="iframe" value="<iframe width="100%"></iframe>" type="text"/>

See the quotes from the width conflict with the delimiting quotes of value.

You can solve this simply by changing the double quotes of value in single quotes:

<input name="iframe" value='<?php echo $iframe;?>' type="text"/>
                           ↑                     ↑

With this there will be the break of the delimiter value, being like this:

<input name="iframe" value='<iframe width="100%"></iframe>' type="text"/>

Or using the function htmlspecialchars:

<input name="iframe" value="<?php echo htmlspecialchars($iframe);?>" type="text"/>
