ColdFusion Tutorial
Listing images on the server
This tutorial will give you a list over images *.gif, *.jpg and *.png in your images directory on your server.
If the list gives you no images, you have to change the path settings in <cfset Img_Dir? statement.
Contact your hosting company, if you not sure what is the correct path.
When you run this example, a list of all the *.jpg, *.gif and *.png images will be displayed. Click on the name of the image and the image will be displayed in your browser.
Use the <cffile tag, for delete, rename and upload new images to your server.
Example:
|
<!--- Set directory on your server to scan for the images.
The ExpandPath() function is used to get the absolute filesystem path on your server.
Set the name of your domain, example www.your_domain.com --->
<cfset domain_name = "your_domain" >
<!--- Set directory on your server to scan for the images. --->
<cfset Img_Dir = ExpandPath ("../#domain_name#/images") >
<!--- Put this test code here to check if your path settings is correct.
Comment out the lines when you have correct path.--->
<cfoutput>#Img_Dir#</cfoutput>
<cfabort>
<!--- End of comment out lines. --->
<!--- Start queries off image files. --->
<!--- Query for *.jpg files --->
<cfdirectory
action = "List"
directory = "#Img_Dir#"
filter = "*.jpg"
name = "Get_Jpg" >
<!--- Start query for *.gif files --->
<cfdirectory
action = "List"
directory = "#Img_Dir#"
filter = "*.gif"
name = "Get_Gif" >
<!--- Start query for *.png files --->
<cfdirectory
action = "List"
directory = "#Img_Dir#"
filter = "*.png"
name = "Get_Png" >
<!--- Then we use query-of-query to combine the 3 queries with SQL union, and sort the result by filename. --->
<cfquery dbtype = "query" name = "Get_Images" >
select * from Get_Jpg
union
select * from Get_Gif
union
select * from Get_Png
order by name
</cfquery>
<cfoutput>
There are #Get_Images.RecordCount# images in #Img_Dir#:
<br>
<ol>
<cfloop query = "Get_Images" >
<li> <a href = "#Img_Dir#/#name#" > #Get_Images.name# </a>
</li>
</cfloop>
</ol>
</cfoutput>
