When creating node to Drupal via XML-RPC, Image Field parameter is not submitting when others are

Question

I'm testing XML-RPC to create a node to drupal using Post Man (chrome extension) and successfully done receiving 200 OK. But the problem is a specific field called "field_answer_with_image" is still blank in the node I created. I think something is wrong with my structure. Here's taxonomy of field_answer_with_image.

Here's my xml structure for creating the node.

<?xml version="1.0" encoding="UTF-8"?><methodCall>
<methodName>node.create</methodName>

Answer 1

You need to create the image first, then create the node using the file ID in a second step.

Step 1:

<?xml version="1.0" encoding="UTF-8"?>
<methodCall>
   <methodName>file.create</methodName>
   <params>
      <param>
         <value>
            <struct>
               <member>
                  <name>filename</name>
                  <value>
                     <string>Dummy.jpg</string>
                  </value>
               </member>
               <member>
                  <name>filesize</name>
                  <value>
                     <int>440048</int>
                  </value>
               </member>
               <member>
                  <name>file</name>
                  <value>
                     <string>$BASE64$</string>
                  </value>
               </member>
               <member>
                  <name>filepath</name>
                  <value>
                     <string>public://Dummy.jpg</string>
                  </value>
               </member>
            </struct>
         </value>
      </param>
   </params>
</methodCall>

This returns you an XML value with an 'fid' field. Find its matching 'value', an integer.

Then to create the node in step 2 (assume fid = 170):

<?xml version="1.0" encoding="UTF-8"?>
<methodCall>
   <methodName>node.create</methodName>
   <params>
      <param>
         <value>
            <struct>
               <member>
                  <name>type</name>
                  <value>
                     <string>dummy_content_type</string>
                  </value>
               </member>
               <member>
                  <name>title</name>
                  <value>
                     <string>Dummy&gt; 123456</string>
                  </value>
               </member>
               <member>
                  <name>field_dummy</name>
                  <value>
                     <struct>
                        <member>
                           <name>und</name>
                           <value>
                              <array>
                                 <data>
                                    <value>
                                       <struct>
                                          <member>
                                             <name>type</name>
                                             <value>
                                                <string>image</string>
                                             </value>
                                          </member>
                                          <member>

                                             <value>
                                                <string>170</string>
                                             </value>
                                          </member>
                                          <member>
                                             <name>uid</name>
                                             <value>
                                                <string>1</string>
                                             </value>

                                                <string>Dummy.jpg</string>
                                             </value>
                                          </member>
                                          <member>
                                             <name>filesize</name>
                                             <value>
                                                <string>44408</string>

                                 </data>
                              </array>
                           </value>

                     </struct>
                  </value>
               </member>
            </struct>
         </value>
      </param>
   </params>
</methodCall>

This will return a node ID similarly to the previous post request.

Works in Drupal 7.
