functions

[dvayne]

Write a function to print out on html <img> tag. The function should accept a mandatory argument of the image url, optional arguments for alt, height, and width.

 

example:

if you enter pic.jpg in this form

image URL: <br />
<input type="text" name="url" />
alt(optional): <br />
<input type="text" name="alt" />
height(optional): <br />
<input type="text" name="height" />
width(optional): <br />
<input type="text" name="width" />
<input type="submit" value="Submit"/>

 

the output:

<img src="pic.jpg">

 

Any help would be appreciated.

Read the rules. This forum isn't for us to write functions/code for you. Also this is a stupid code. Wouldn't it be faster to type out the literal <img> tag and stuff than to use this? It's about the same amount of time.

 

But since this is relatively easy, it would go something like this:

<?php
if ($_POST['submit']){
$url = (empty($_POST['url']))? "" : $_POST['url'];
$alt = (empty($_POST['alt']))? "" : $_POST['alt'];
$height = (empty($_POST['height']))? "" : $_POST['height'];
$width = (empty($_POST['width']))? "" : $_POST['width'];
echo ($url == "")? "URL not entered" : "<img src='$url' alt='$alt' width='$width' height='$height' />";
?>
<form method='post'>
image URL: <br />
<input type="text" name="url" />
alt(optional): <br />
<input type="text" name="alt" />
height(optional): <br />
<input type="text" name="height" />
width(optional): <br />
<input type="text" name="width" />
<input type="submit" name='submit' value="Submit"/>
</form>

no reason to make the server do it, use javascript.

Teacher insists on PHP for homework assignments.

Instructions on writing some code written in the imperative mood strongly suggests that it is a task somebody else has assigned to you. Seeing as this is rather trivial it's most likely homework and this is not a "do my homework for me" website.
