Un saluto a tutti.
Mi occorerebbe sapere se e come sia possibile integrare una visualizzazione di anteprima (in pagina web) dei dati da inviare tramite form (nel mio caso un pannello di invio articoli, che non utilizza database mysql).
Questo è lo script del mio pannello (Article Manager):
<?
include ("template.inc");
include ("config.php");
$subject = $_POST[subject];
$summary = $_POST[summary];
$passwd = $_POST[passwd];
$date = $_POST[date];
$body = $_POST[body];
$article_id = $_POST[article_id];
#foreach($GLOBALS as $a => $b){ print "<li>$a => $b";}
$summary_template = "t_summary.html";
$article_template = "t_article.html";
$max_summary = 5;
function summary_page ($subject, $date, $summary, $article_id)
{
global $summary_template;
$t = new Template();
$t->set_file("SummaryPage", $summary_template);
$article_url = "article_".$article_id.".html";
$date = nl2br($date);
$summary = nl2br($summary);
$t->set_var( array(
"subject" => $subject,
"date" => $date,
"summary" => $summary,
"article_url" => $article_url
));
$t->parse("Summary", "SummaryPage");
return $t->get_var("Summary");
}
function main_page ($subject, $date, $summary, $article_id, $body)
{
global $article_template;
$t = new Template();
$t->set_file("ArticlePage", $article_template);
$article_url = "article_".$article_id.".html";
$date = nl2br($date);
$summary = nl2br($summary);
$body = nl2br($body);
$t->set_var( array(
"subject" => $subject,
"date" => $date,
"summary" => $summary,
"body" => $body,
"article_url" => $article_url
));
$t->parse("Article", "ArticlePage");
return $t->get_var("Article");
}
function add_article($filename, $news)
{
if(file_exists($filename)){
$fh = fopen($filename, "r");
$old_news = fread($fh, filesize($filename));
fclose($fh);
}
/* TODO: Multipage articles
preg_match_all("<!--ARTICLE PAGE=(\d*)-->", $old_news, $matches;
if( count($matches[0]) >= $max_summary){
$oldfilename = $filename.($matches[0][0]+1);
}
*/
$fh = fopen($filename, "w");
$news = stripslashes($news);
fwrite($fh, "\n<!--ARTICLE-->\n$news $old_news");
fclose($fh);
}
if(strcmp($subject, "")){
if(!(strcmp($passwd, $password))){
add_article("article_summary.html", summary_page($subject, $date, $summary, $article_id));
add_article("article_$article_id.html", main_page($subject, $date, $summary, $article_id, $body));
echo "<p> <a href=article_$article_id.html>Article</a> has been added! <p>";
}else{
echo "<p><b> Password is wrong! </b>";
}
}
?>
E questo il form da cui inviare i dati:
<form action=news.php method=post>
<table border=0>
<tr> <td> (Password): </td><td> <input type=password name=passwd size=20> </td></tr>
<tr> <td> Subject: </td><td> <input type=text name=subject size=50> </td></tr>
<tr> <td> Article ID: </td><td> <input type=text name=article_id value=<? echo date("Y_m_j_is"); ?> size=30> </td></tr>
<tr> <td> Date/Author/etc: </td><td> <textarea name=date rows=2 cols=50 wrap=soft><? echo date("M j, Y\n"); ?>Author: </textarea> </td></tr>
<tr> <td> Summary: </td><td> <textarea name=summary rows=5 cols=50 wrap=soft></textarea> </td></tr>
<tr> <td> Body: </td><td> <textarea name=body rows=15 cols=50></textarea> </td></tr>
</table>
<input type=submit name=submit value=Add>
</form>
Il tutto è piuttosto semplice..ma non riesco a trovare il modo di inserire un'anteprima web dell'articolo da postare..
Chiedo il vostro aiuto 
Sera a tutti, ragazzi.
