#19643 reviewing defect (bug)

Allow array for $extra_fields in request_filesystem_credentials

Reported by: griffinjt Owned by: dd32

Severity: minor Version: 3.0

The current implementation for passing extra fields through request_filesystem_credentials() does not allow for an array of data to be passed. I came across this issue when trying to process a bulk installation of plugins with my plugin installation class. My patch fixes this from what I can tell and doesn't break anything that I can see from my testing.

allow array of data to be passed through $extra_fields

That'll issue a PHP Notice on any $extra_fields which aren't in the incoming $_POST array. That's why there's a isset() call there

#3 @griffinjt

It's late - forgive me. :-) That should fix the error warnings now and still works fine as far as I have tested.

#4 @GaryJ

Instead of doing an is_array() check and duplicating the echo line, why not cast $_POST['field'] to an array and just have the foreach?

#5 @griffinjt
9 years ago

Doing that won't allow for the input name attribute to be set as an array. That's why I had the two echo lines.

#6 @griffinjt

Any word on this? Again with testing I haven't run into any bugs and it works perfectly for passing an array of data from a previous post entry.

Any word on this?

Most of us are taking a break after 3.3's release. 3.4 dev will be starting after the holiday season and people will look over it then most likely. Have patience.

Ok,cool. No worries!

Ok, here's my feeble attempt at providing a solution that will catch any type of value submitted via $extra_fields and parse it correctly within the input field. Because my knowledge of recursion is shoddy at best, I came up with this function instead.

All it does is sanitize and store all the data passed via $extra_fields into an array and then builds a query string based on that data. Then I just run through the query string and make input fields.

It works in all my testing. I don't know if this is the -best- method, but it is a -working- method that can at least get the ball rolling so that no data is lost when attempting to pass it once the user hits "Proceed".

callback function to accept any type of extra field

#12 @griffinjt

Just updated the patch to use (the newly discovered to me) WP's build_query function. Would love to get some feedback on this - no more losing data when having to enter FTP credentials. :-)

Alternate patch - handles multi-dimensional arrays

#14 @kurtpayne

Submitting an alternate patch. This will handle multi-dimensional arrays, too. E.g.

<input type="hidden" name="field1[]" value="value1" />
<input type="hidden" name="field1[]" value="value2" />
<input type="hidden" name="field1[]" value="value3" />
<input type="hidden" name="field2[deep][array][value]" value="value4" />
<input type="hidden" name="field3[][][]" value="value5" />
<input type="hidden" name="field4" value="value6" />

And the corresponding php:

$form_fields = array ( 'field1', 'field2', 'field3', 'field4' );
request_filesystem_credentials($url, $method, false, false, $form_fields) );

I'm testing this with Otto's test filesystem plugin.

Wondering what the status is of this. Ran into this bug myself as well.

Code-wise, I'm in favour of @kurtpayne's patch, through I'd prefer to see the array_print as a proper function to stay in line with most other WP code.

@dd32: Care to follow up here?

#19 @dd32

Before considering any changes here, we'll be best off seeing what happens with the inline-install #29820.
This screen is mostly going to disappear, or need to be rewritten for that I believe.

#20 @jrf
6 years ago

@dd32 I'm not sure I understand why as file read/writes can need to be done quite legitimately outside of the context of plugin installation. This is about the FileSystem API, not necessarily about plugin installation/upgrade etc.

#21 @jrf

What can be done to move this forward ?
