i created few buttons , onlick of button url , filename send dynamic array , when click dropbox saver button want saver function uses dynamic array send files dropbox. current code gives me error:missing files.see documentation.
its seems didnt save data correctly array , didnt pass correctly saver funciton. 1 me fix problem.thanks
note: want use dynamic array instead of hardcoded url , filenames shown here:
edited: add options.files = files; before calling dropbox.save , declared array outside addtoarray function . error:g undefined @ dropins.js(line 1).
files: [ {'url': '<?php echo $imagepath1_value; ?>', 'filename': '1.jpg'}, {'url': '<?php echo $imagepath2_value; ?>', 'filename': '2.jpg'}, {'url': '<?php echo $imagepath3_value; ?>', 'filename': '3.jpg'}, ], dropbox api js:
<script type="text/javascript" src="https://www.dropbox.com/static/api/2/dropins.js" id="dropboxjs" data-app-key="xxxxxxxxxxxxxx"></script> <script> saveing fileurl , filename array function:
var i=1; files = new array(); function addtoarray(a,b){ alert("url:"+a+"\nfilename:"+b); files[i] = { url: +a, filename: +b }; i++; }; dropbox savers function:
function saver(){ var options = { //here want use array created above instead of hardcode filepath , filenames //files: [ // can specify 100 files. // ... //{'url': '<?php echo $imagepath1_value; ?>', 'filename': '1.jpg'}, //{'url': '<?php echo $imagepath2_value; ?>', 'filename': '2.jpg'}, //{'url': '<?php echo $imagepath3_value; ?>', 'filename': '3.jpg'}, //], // success called once files have been added user's // dropbox, although may not have synced user's devices yet. success: function () { // indicate user files have been saved. alert("success! files saved dropbox."); }, // progress called periodically update application on progress // of user's downloads. value passed callback float // between 0 , 1. progress callback guaranteed called @ least // once value 1. progress: function (progress) {}, // cancel called if user presses cancel button or closes saver. cancel: function () {}, // error called in event of unexpected response server // hosting files, such not being able find file. callback // called if there error on dropbox or if user on quota. //error: function (errormessage) {} error:function (errormessage) { alert("error: " + errormessage); } }; options.files = files; dropbox.save(options); }; </script> body of html:
<body> <button onclick="addtoarray('<?php echo $imagepath1_value; ?>','filename1.jpg')">add array</button> <button onclick="addtoarray('<?php echo $imagepath2_value; ?>','filename2.jpg')">add array</button> <button onclick="saver()">save</button>
you can build files array want, long options.files array contains necessary information when call dropbox.save. e.g., append shared files variable when call addtoarray (right looks making new 1 each time) , set options.files = files before calling dropbox.save.
