APIs: Save the contents of a TextBox, Label, variable, etc. to the SDCARD

[Scott Ferguson]

This uses the Web component to send the contents of a block in App Inventor to a php server where it is echoed back to a GotFile block and saved in a designated file on the sdcard.
This would allow saving data from TinyDB also on the sdcard.

The php script to echo the text to a file: <?PHP echo file_get_contents('php://input'); ?>

I'm not fimiliar with php. How do I use this. Make an html file with it?

[Scott Ferguson]

You can get free web hosting at sites like 000webhost.com. Then post a php file containing the above code. and access it with AI's web component.
No html is involved.

Thanks for sharing that. So I just drop the PHP code into the editor of say a subpage and when that page is called on, it processes it?

[Scott Ferguson]

That's all there is to it!

I now adjusted your example for server which do not offer to set always_populate_raw_post_data to on
you can find this workaround here: http://puravidaapps.com/save.php

Thanks for the link and providing a solution, Taifun. I like the idea of having a password for security purposes also.

How can we avoid overwriting a file? If a file with name hello.txt exists, create hello2.txt , is that possible?

Also, after saving to a file on SD , after my text there always is some kind of comment with a link and more stuff, this must be coming from the host im using right? (000webhost)

[Scott Ferguson]

1. I cannot think of a way to 'sense' if a file exists as the process now is 'dumb'. There may be a way to do a read test with javascript first before doing the download. Taifun might have a suggestion there.
2. yes. I need to turn that off. Thanks for the heads up.

But noew it works fine!

Thank You for the script!

is that your server?
can't you set the flag always_populate_raw_post_data to on on your server?
did you follow these instructions http://puravidaapps.com/save.php to install the PEAR::PHP_Compat package ?

Scott,  I have been using the both get_url.php  and openlocalfile.php for over a year now .  Everything has been working great! 

 

Today, 000webhost had a sever problem and had a statement on the server that they would be back up in 2-3 hours.  During that time I was not able to see my website at all.  Now the server is back online and I am able to see my website.  Also, both of the PHP files are there.  However my PHP files no longer return the html that I send.  Can you check and see if yours still work on 000webhost?  I have a service ticket open at 000webhost but have not received a reply yet.  I am on server #44 if it matters... 

 

I am also wondering if the file access rights might have changed. The original server error message was that a disk drive was reporting a 'read only file system' error.  I can't remember if I need to change the permissions for read write on the PHP files.

 

 

When I send HTML from my AppInventor app, this is what I get in return:

<!-- Hosting24 Analytics Code -->
<script type="text/javascript" src="http://stats.hosting24.com/count.php"></script>
<!-- End Of Analytics Code -->

 

 

Thanks for all your help!!!!

[Scott Ferguson]

Here is a link to turn off the analytics code: http://members.000webhost.com/analytics.php

Then try again.

Thanks,  I turned off the analytics code and now I get nothing in the response.

[Scott Ferguson]

This is what I get:

BTW you are welcome to use my server for testing.

I used: http://www.aiapis.org/php/openlocalfile.php in this example. My server has changed and all php files are in the php folder.

This appears to be coming from AI itself rather than the server. See: https://github.com/mit-cml/appinventor-sources/blob/master/appinventor/components/src/com/google/appinventor/components/runtime/util/ErrorMessages.java

and https://www.google.com/search?q=error+1103&oq=error+1103&aqs=chrome..69i57j0l5.3046j0j8&sourceid=chrome&espv=210&es_sm=93&ie=UTF-8#es_sm=93&espv=210&q=%22unable+to+post+or+put+the+text%22

I would appear that something has changed on the server to prevent the app from working? I would not know what, however.

[Scott Ferguson]

I cannot get to my server at all. aiapis.org is down. :(

Scott, thanks again for your help.  I did use your server and everything worked, so I knew it was a server issue... That helped a lot!!!!

 

Ended up finding out the permissions did get changed.

 

>>> permissions: all php files should be chmod 644 (and if they are within a folder, the folder should be chmod 755)

 

Once I changed the permissions back, everything is working great again!!!

 

I also got tired of Free server tech support and purchased a domain and hosting service.  I think I'm going to like!!!

 

(I understand I wasn't paying anything, what tech support should I expect.  But, everything was working great until they had a drive crash and changed everything to read only.)

 

[Scott Ferguson]

Thanks for the chmod 644 tip. That may help someone in the future. hAPPy INVENTORing!
