If you don't like the "wordpress@yourdomain.com" email format either – you can change that address via a plugin like: wp-mailfrom. However, again – whatever address you set it to in there – still needs to exist in your account. So if you prefer to have the from emails be ilovewordpress@yourdomain.com; make sure there is a ilovewordpress@yourdomain.com email account, forwarder or autoresponder.

Of course there's another way – but I never knew it until recently. It's incredibly simple and built right into Firefox. Just right-click on a page, select "view page info" from the menu. Then on the pop-up click the "media" tab. That will list all the images on the page, both ones called from the HTML and the CSS.

You can click on individual image and then click "Save As" to download one in particular you want. Or if you want all of them, hold down the shift key and select all the lines. Then click "save as" to save them down to your computer.

I found this tip here: http://www.webdeveloper.com/forum/showthread.php?t=212610

If you have Adobe Photoshop, to make this change, go to the "Image" menu, select "Mode" then see if "CMYK" is checked. If so, select "RGB" to change the color mode. Save and upload your image again and make sure you're linking to the new version.

<php if (strpos($_SERVER['HTTP_USER_AGENT'],"iPhone")) { ?>
... CUSTOM CSS FOR IPHONE...
<php } ?>

This will also work for iPhones and iPod Touch:

<php if (strstr($_SERVER['HTTP_USER_AGENT'],'iPhone') || strstr($_SERVER['HTTP_USER_AGENT'],'iPod')) { ?>
... CUSTOM CSS...
<php } ?>

That's great and all – but then suddenly one day it stopped working. Going back through what changed on the site, I realized one thing we added was a cache plugin. DOH! So the page gets cached without the custom CSS for the iPhone – the iPhone calls up the site but gets served the cached page (non-iPhone version)… Yeah, that would do it.

So I found this solution:

<!--[if !IE]>-->
<style type="text/css">
@media only screen and (max-device-width: 480px) {
.... CUSTOM CSS HERE....
}
</style>
<!--<![endif]-->

or of course you can pull in a whole stylesheet for the iphone:

<!--[if !IE]>-->
<link media="only screen and (max-device-width: 480px)" rel="stylesheet" type="text/css" href="iphone.css" />
<!--<![endif]-->

I'm not sure of what other factors played a role (the fact that the element was in a absolute positioned container, or that the immediate container to the flash element was in a float) but I had the call to the swfobject javascript in the BODY tags of the html (not within the head tags). This was apparently causing Firefox to not display the flash. Simply moving the swfobject javascript code within the head tags of the html instantly fixed the problem.

I know I've used swfobject inside the body before – so I'm sure there's something else that contributed to the problem.

<input type="image" SRC="blahButton.gif" ALT="blah" name="blah" id="blah" value="blah" />

Which works fine when simply submitting the form when there's ONE button. But on one page I had TWO buttons. The form would submit to itself, and then depending on which button was clicked, I would handle the form as appropriate. Worked fine in firefox – nothing happened in IE. I found this page in a search.

What I had been doing was simply (in php)

if (isset($_POST["blah"])) {
//do stuff
} else if (isset($_POST["blahblah"])) {
//do different stuff
}

What fixed the problem was changing that code to this:

if (isset($_POST["blah_x"])) {
//do stuff
} else if (isset($_POST["blahblah_x"])) {
//do different stuff
}

Now my form works…

I was asked to create a "look up" tool that would sort of "translate" one piece of text to another. The user would enter in the first piece of text, and then they'd be given the "value". Oh, and this list updates every few months or so.

At first I started looking into creating a database, and writing a script that would update that database – problem was that creating and accessing a database for this project was going to be time consuming and difficult. A server-side script would have been the best solution under the circumstances. A few hours this morning searching around turned up this "dictionary" script.

I'm actually being given the the text and values in excel, so I just need to create a sort of "template" in excel that formats everything so it will look like the code – and then I just copy and paste it all into the ASP file.

So here's kind of what I have in my file:

SET TextToNumber=CreateObject("Scripting.Dictionary")
TextToNumber.Add "name", "292949"
TextToNumber.Add "date", "123414"
etc. etc…

Then my form looks like this:

<form name="textlookup" action="lookup.asp" method="post">
Text: <input type="text" name="text" value="" /><br>
<input type="submit" name="submit" value="Look Up Text Number" /></form>
Text: <% Response.Write(Request.Form("text")) %><br>
Number: <%
TextValue=Request.Form("text")
NumberValue=TextToNumber(TextValue)
Response.Write(NumberValue)
%>

Using "break" in the middle of a while loop will break the loop entirely. (no more looping)

So this code

<?php
$i = 0;
while ($i < 5) {
$i++;
if ($i%2) {
echo "value = " .$i . " – inside if<br>";
continue;
}
echo "value = " .$i . " – outside if<br>";
}
?>

Will produce this:
value = 1 – inside if
value = 2 – outside if
value = 3 – inside if
value = 4 – outside if
value = 5 – inside if

Where as this

<?php
$i = 0;
while ($i < 5) {
$i++;
if ($i%2) {
echo "value = " .$i . " – inside if<br>";
break;
}
echo "value = " .$i . " – outside if<br>";
}
?>

Will produce this:
value = 1 – inside if
