Hello,

I'm trying to loop through this json link...
<!--- Get the JSON Feed --->
<cfhttp url="http://www.geoplugin.net/extras/nearby.gp?limit=50&radius=50&format=json">

<!--- JSON data is sometimes distributed as a JavaScript function.
     The following REReplace functions strip the function wrapper. --->
<cfset theData=REReplace(cfhttp.FileContent,
        "^\s*[[:word:]]*\s*\(\s*","")>
<cfset theData=REReplace(theData, "\s*\)\s*$", "")>

<!--- Test to make sure you have JSON data. --->
<cfif !IsJSON(theData)>
    <h3>The URL you requested does not provide valid JSON</h3>
    <cfdump var="#theData#">

<!--- If the data is in JSON format, deserialize it. --->
<cfelse>
    <cfset cfData=DeserializeJSON(theData)>
    <!--- Parse the resulting array or structure and display the data.
             In this case, the data represents a ColdFusion query that has been
             serialized by the SerializeJSON function into a JSON structure with
             two arrays: an array column names, and an array of arrays,
             where the outer array rows correspond to the query rows, and the
             inner array entries correspond to the column fields in the row. --->
    <!--- First, find the positions of the columns in the data array. --->
   
            <cfoutput>
            <cfloop collection="#cfData#" item="key">
                  <cfloop array="#cfData['geoplugin_place']#" index="struct2">
                        
                  </cfloop>
            </cfloop>
            </cfoutput>
</cfif>

without having any idea what the data looks like, this is based on what it appears you're trying to do.   First, you are looping a structure and the structure is made up of arrays... ?


<cfloop collection="#cfData#" item="key">
   <!--- the result of this would be  cfData[key],  
         IF this is an array, then you would loop it like this: ---->
   <cfloop index="pos" from="1" to="#arrayLen(cfData[key])#">
        #cfData[Key][pos]#
   </cfloop>
</cfloop>

hi,

I modified your code, check below:

<!--- Get the JSON Feed --->
<cfhttp url="http://www.geoplugin.net/extras/nearby.gp?limit=50&radius=50&format=json">

<!--- JSON data is sometimes distributed as a JavaScript function.
     The following REReplace functions strip the function wrapper. --->
<cfset theData=REReplace(cfhttp.FileContent,
        "^\s*[[:word:]]*\s*\(\s*","")>
<cfset theData=REReplace(theData, "\s*\)\s*$", "")>

<!--- Test to make sure you have JSON data. --->
<cfif !IsJSON(theData)>
    <h3>The URL you requested does not provide valid JSON</h3>
    <cfdump var="#theData#">

<!--- If the data is in JSON format, deserialize it. --->
<cfelse>

    <cfset cfData=DeserializeJSON(theData)>
    <!--- <cfdump var="#cfData#"> --->
    <!--- Parse the resulting array or structure and display the data.
             In this case, the data represents a ColdFusion query that has been
             serialized by the SerializeJSON function into a JSON structure with
             two arrays: an array column names, and an array of arrays,
             where the outer array rows correspond to the query rows, and the
             inner array entries correspond to the column fields in the row. --->
    <!--- First, find the positions of the columns in the data array. --->
   
            <cfoutput>
              <cfloop array="#cfData#" index="i"> <!--- Loop for array --->
                <cfloop collection="#i#" item="k"> <!--- loop for structure inside array --->
                   #i[k]#
                </cfloop>  
                <br/><br/>
              </cfloop>  
            <!--- <cfloop collection="#cfData#" item="key">
                  <cfloop array="#cfData['geoplugin_place']#" index="struct2">
                       
                  </cfloop>
            </cfloop> --->
            </cfoutput>
