I have an base64 picture string in coldfusion. How can I save this image

  • 0

I have an base64 picture string in coldfusion.

How can I save this image blob into the database without storing to filedisk?
My function.

<cfset base64string="base64picturestring">
<cfimage source="#ImageReadBase64("data:image/png;base64,#base64string#")#"
destination="c:\picture.png" action="write" overwrite="true">
<cffile action="readbinary" file="c:\picture.png" variable="ImageData"/>

INSERT INTO imagedb (imageblob)
VALUES (<cfqueryparam cfsqltype="cf_sql_blob" value="#ImageData#" />)

But I don’t want to save image on the hard drive.
I need this.

base64—-imageblob—-database

Any help?

    You could use the in-memory filesystem:

    <cfset base64string="base64picturestring">
<cfimage source="#ImageReadBase64("data:image/png;base64,#base64string#")#"
destination="ram://src/picture.png" action="write" overwrite="true">
<cffile action="readbinary" file="ram://src/picture.png" variable="ImageData"/>
<cffile action="delete" source = "ram://src/picture.png"> 

INSERT INTO imagedb (imageblob)
VALUES (<cfqueryparam cfsqltype="cf_sql_blob" value="#ImageData#" />)
