BrianM Posted May 12, 2008 Share Posted May 12, 2008 Here is a script I'm using to display a table from a database and when you click on any field in a row which has content, the entire row becomes editable. After having a bit of trouble I finally got the database to update just using a set number/text I put in the update page, but now I'm trying to figure out which variable to use from the page displaying the table to get the update.php page to update the database as it should. index.php <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <?php mysql_connect("localhost", "brian", ""); mysql_select_db("example"); function returnheaders() { $sql = mysql_query("SELECT * FROM example WHERE ID=1") or die(mysql_error()); $array = mysql_fetch_array($sql); //print_r($array); foreach($array as $key => $value) { if(!is_numeric($key) && $key != "ID") { echo("<td id=\"header_$key\">$key</td>\n"); } } } function returndata() { $sql = mysql_query("SELECT * FROM example"); while($row = mysql_fetch_array($sql)) { echo("<tr id=\"dataset_row".$row['ID']."\">\n"); foreach($row as $key => $value) { if(!is_numeric($key) && $key != "ID") { echo("<td id=\"".$key.$row['ID']."\" nowrap><a id=\"".$key."_".$row['ID']."_value\" href=\"javascript:edit_row(".$row['ID'].");\">".$value."</a></td>\n"); } } echo("</tr>\n"); } } function loaddynamicjava() { echo("<script type=\"text/javascript\">\nvar readylight = true;\nfunction edit_row(row) {\nvar currentval;\n"); $sql = mysql_query("SELECT * FROM example WHERE ID=1") or die(mysql_error()); $array = mysql_fetch_array($sql); foreach($array as $key => $value) { if(!is_numeric($key) && $key != "ID") { echo("currentval = document.getElementById(\"".$key."_\"+row+\"_value\").innerHTML;\n"); echo("document.getElementById(\"".$key."\"+row).innerHTML = "); if($key == "PermitProcess") echo("'<input type=\"button\" name=\"save\" value=\"Save\" onClick=\"savedata('+row+');\">"); else echo("'"); echo("<input type=\"text\" id=\"".$key."_'+row+'\" name=\"".$key."_'+row+'\" value=\"'+currentval+'\" />';\n"); } } echo("}\nfunction savedata(row) {\nif(!ready) { alert(\"System is still saving other data\"); return; }\nready = false;\nvar currentdata;"); foreach($array as $key => $value) if(!is_numeric($key)) if($key == "ID") echo("document.getElementById(\"ID\").value = row;\n"); else echo("document.getElementById(\"".$key."\").value = document.getElementById(\"".$key."_\"+row).value;\n"); echo("document.getElementById(\"theform\").submit();\n"); foreach($array as $key => $value) if(!is_numeric($key) && $key != "ID") { echo("currentdata = document.getElementById(\"".$key."_\"+row).value;\n"); echo("document.getElementById(\"".$key."\"+row).innerHTML = '<a href=\"javascript:edit_row('+row+');\" id=\"".$key."_'+row+'_value\">'+currentdata+'</a>';\n"); } //echo("}"); echo("}\nfunction nowready() { ready = true; }</script>"); } function returnformfields() { $sql = mysql_query("SELECT * FROM example LIMIT 1"); $array = mysql_fetch_array($sql); foreach($array as $key => $value) if(!is_numeric($key)) echo("<input type=\"hidden\" name=\"".$key."\" id=\"".$key."\">\n"); } ?> <?php loaddynamicjava(); ?> </head> <body> <table border="1" cellpadding="0" cellspacing="0"> <tr class="header"><?php returnheaders(); ?></tr> <?php returndata(); ?> </table> <form action="update.php" method="post" target="hiddenframe" name="theform" id="theform"> <?php returnformfields(); ?> </form> <iframe src="about:blank" style="display: none;" name="hiddenframe" id="hiddenframe" onLoad="nowready();">This Page Requires iFrames Which Your Browser Does not support</iframe> </body> </html> update.php <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Untitled Document</title> </head> <?php mysql_connect("localhost", "brian", ""); mysql_select_db("example"); $sql = "UPDATE example SET Required = 'what_var_do_i_place_here??'

benphp Posted May 12, 2008 Share Posted May 12, 2008 You can do it by either adding a <form> around each row and use the (name="ID_'+row+'") for the update variable, or you can put a form around the whole page, then use arrays (name="ID[]") for your variables and loop them on your update page - using ID as the key of course.

soycharliente Posted May 12, 2008 Share Posted May 12, 2008 First of all, this is a free forum, if you want a response on your terms, you can advertise for some paid help. Please don't complain about not getting an answer after less than an hour. The variable that goes there is defined by you. I hope that makes sense. When you grab the data from the form, you save it to a variable. Correct? What data do you want to go in there?

benphp Posted May 12, 2008 Share Posted May 12, 2008 Now that I look at it again, you'll probably want to use ID[] array type names for your variable names, because it looks like you want to edit multiple rows then update them all, no? If so, you'll need to define the variables as arrays. <form> <input type="text" name="ID[]" value="54"> <input type="text" name="ID[]" value="43"> <input type="text" name="ID[]" value="12"> </form> then loop it on your update page: $ID[] = $_POST['ID']; foreach ($ID as $temp) { sql = "update mytable where ID = $temp "; } Link to comment https://forums.phpfreaks.com/topic/105333-what-variable-do-i-use/#findComment-539540 Share on other sites More sharing options...
