Is looping over cfhttp possible?

[cjdunkerley]

Hi,

Please can some one let me know if it is possible to loop over cfhttp. I have
looked everywhere for an answer but can not get the code to work. The code I
loop over is below but it only gets the first file in the loop. I don't know
what to try next!

<cfhttp method="Get" url="http://www.theurl.com/images/#imagesArray#"
path="D:\thegpg\htdocs\images\mrm_images\">

If it not possible does anyone know another method of getting lots of images
from a remote server. FTP is not curently an option.

Thanks,
Chris.

It is possible to loop over cfhttp, I used it loads of times.

Can you please post your code again, but use the Attach Code function at the
bottom some of the code is messing up the formating but it will show properly
if you post it using Attach Code.

Hi Simon,

Here is the code. It only gets the first image in the array? I can not make
it continue through the rest of the images, I have tried everything I can think
of and looked in the Forums for answers.

Any ideas?

Regards,
Chris.

<cfquery datasource="thegpg" name="all_mrm_data">
SELECT img_main, img_location, img_description, image1, image2, image3, image4
FROM PropertiesWOwner
WHERE DataProvider = 'MRM'
</cfquery>

<cfset qrows = 10>
<cfoutput>#qrows#</cfoutput> properties to get images for<br>
<cfset imagesArray = arraynew(1)>
<cfloop query="all_mrm_data" startrow="1" endrow="#qrows#">
<cfset ArrayAppend(imagesArray, "#img_main#")>
</cfloop>
<cfdump var="#imagesArray#">


<cfloop from="1" to="#arraylen(imagesArray)#" index="i">
<!--- See if we have this image already --->
<cfif not fileExists("D:\thegpg\htdocs\images\mrm_images\#im agesArray[1]#")>
<cfhttp method="Get"
url="http://www. the url .com/images/#imagesArray[i]#"
path="D:\thegpg\htdocs\images\mrm_images\">
</cfhttp>
<cfoutput>Got image #imagesArray[1]#</cfoutput><br>
</cfif>
</cfloop>

Your problem is here:-

<cfif not fileExists("D:\thegpg\htdocs\images\mrm_images\#im agesArray[1]#")>

change the array reference to i not 1.

The way it is now once the first image is found and saved to the disk this
will always be false and so will not get anymore images.
