[form validation driving me nuts]

Hi Im really a PHP programmer and trying to cobble together some code for a very simple form validation, what i need to do is if a select value is at its default state of "Choose size" I need to make an alert saying choose size before sending the form.

 

In IE it keeps saying this page contains errors "object doesnt support this method or property "but functions ok, however this is stopping me from adding another zooming in javascript for images.

 

Could someone Please amend or let me know what im doing wrong.

 

in the head

<script type="text/javascript">
function submitform(){
var sizevar = document.getElementById("size");
if(!madeSelection(sizevar, "Please Choose a Size")){

}
}
function madeSelection(elem, helperMsg){
if(elem.value == "choose"){
	alert(helperMsg);
	elem.focus();
	return false;
}else{
	document.addtocart.submit();
}
}
</script>

 

bit of a mismatch of code, dont know javascript

 

and the link to submit the form

 

<a href="javascript: submitform()" class="buy">Add to shopping bag</a>

 

Thanks!

 

[unexpected result from subtraction]

OK, fixed it using bcsub (1481.00,1480.99,2)

 

How weird.

[unexpected result from subtraction]

Hi foodigi,

 

Thanks

 

Did you resolve your issue by rounding?

[Convert XML to mySQL Result]

I'd start by using explode on the xml string on the <row>, then looping the array using str_replace on the </row>, then do the same for <name> and <city> making an php array to hold all the data, then loop through this array to put the data how you need it.

[unexpected result from subtraction]

Hi I'm getting an unexpeted result from the following,

 

<?php
echo 1481.00-1480.99;
?>

 

output = 0.00999999999999

 

Does anyone understand why this is happening?

[Google Map Driving Distances]

Hi I have a list of places of interest which I have their Lat & Lon for, I also have another list of villas of which I'd like to calculate the driving distances between the items.

 

I can output a map with the directions from one point to another, but could I just output the distances between points as a list rather than the directions. Or can I capture the javascript variable and enter into a database to retrive with php to output a list of distances.

 

What id like to achive is something like

Distance to Disney: 2 miles

Distance to Seaworld: 4 miles

Distance to Kennedy Space Center: 15 miles.. etc.

 

Or would I have to manually query every villa for every item and then enter it in a DB

 

I only really know PHP, javascript is new to me hence the lack of knowledge.

 

Google example

[[SOLVED] sql select with exact character matching using wildcard]

Works a treat,

 

Thanks so much

[[SOLVED] sql select with exact character matching using wildcard]

I am building a databse of crossword words.

 

I want to select where word = d?t?

 

I am trying to use select where word like 'd%t%'

 

however when running it I expect to get returned results of the word

 

DATA

 

but it seems to search where d & t are in that order returning for example

 

ADIT, DART

 

etc

 

do I have to get all these results then match character for character through an array or can I do this in my mysql query

 

Many Thanks

[[SOLVED] session timeout]

That looks like all the info I need,

 

thanks

[[SOLVED] session timeout]

How long does it take for a session to timeout,

 

if I have a user logged in on my site, how much time of inactivity will it take before the session is automatically destroyed and they become logged out,

 

i do not use cookies,

 

I have these values in my php info

 

session.cache_expire 180

session.gc_maxlifetime 1440

session.gc_probability 1

 

from what I understand the session is destroyed after 180 minutes of inactivity,

 

but the session has a 1% chance of being garbage collected after 1440 seconds of inactivity (is this destroyed?)

 

so if I wanted all sessions destroyed after the 1440 seconds, should i set the probability to 100

 

or should i change the

session.cache_expire 180

 

to something that would suit me better, i.e. the 1440 seconds,

 

i.e.

session.cache_expire 24,

 

would this always delete the session after 24 minutes,

 

or do both values have to correspond etc,

 

any advice on this would be greatly appreciated,

 

Thanks

[[SOLVED] html tags]

Yeah,

 

But I guess not everyone of there users check input before doing stuff with it, so guess its a failsafe,

I may see if I can get them to remove this restriction, was just so baffled by the behaviour, glad I now have an answer.

 

Thanks Again

Yeah that is the problem,

 

very weird behaviour, I have tested it without

[choosing the hosting server]

What website are you hosting, is it a uk site, if so use a uk host,

 

this is for a seo reason, i.e. sites held on us servers which are actually uk sites will be given less relevance from google.co.uk as google thinks it's a US site,

 

I use eukhost they seem pretty good,

 

I have quite a healthy amount of reseller space, for a relatively cheap amount of money.
