Hello,

I'm loving Inputfield Dependencies in PW 4.

I have the following fields:

Fields:

- columnOption : Page : Input type Select

..... No Section

..... Batch ?id=1016

..... Font Awesome ?id=1017

- batchClass : Text : showIf columnOption=1016 //Batch CSS Class 

- batchDataIcon : Text : showIf columnOption=1016 //Batch Icon Data

- faClass : Text : showIf columnOption=1017 //Font Awesome

Template:

- column : All fields from above

For example:

     I select Font Awesome and faClass:field appears I input fa-code-fork. If I choose another option, content for faClass:field still remains in my template.

How can I check if a selected option is active or not with showIf in a template. I hope I'm making sense. I attached images for you to see.

Code basic : home.php

<?php foreach ($page->column as $c) : ?>

<div class="four columns icons">
    <i class="icon <?php echo $c->batchClass ?>" data-icon="<?php echo $c->batchDataIcon ?>"></i>
    <h3><?php echo $c->title ?></h3>
    <p><?php echo $c->body ?></p>
</div>

<?php endforeach ?>

Thank you!

Super awesome!

That is a crazzzzy form builder!

Thank you!

Code is working now! Thanks!

libs/paypal/ipn.php

<?php
include ("../../index.php");

$productid = $wire->pages->get(1332);

var_dump($productid);
?>

Thank you Pete!

Hello Community,

I have a directory structure like this:

[website]

|- libs // This folder is not part of PW

|- paypal

|- ipn.php

|- site

|- wire

The problem is that I cannot access $pages inside /website/libs/paypal/ipn.php.

Paypal IPN will point to this file: http://mysite.com/libs/paypal/ipn.php

<?php

$productid = $pages->get(1332);
var_dump($productid);

// read the post from PayPal system and add 'cmd'
$req = 'cmd=' . urlencode('_notify-validate');

foreach ($_POST as $key => $value) {
 $value = urlencode(stripslashes($value));
 $req .= "&$key=$value";
}

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: www.paypal.com'));
$res = curl_exec($ch);
curl_close($ch);

// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];

if (strcmp ($res, "VERIFIED") == 0) {
  // check the payment_status is Completed
  // check that txn_id has not been previously processed
  // check that receiver_email is your Primary PayPal email
  // check that payment_amount/payment_currency are correct
  // process payment
}
else if (strcmp ($res, "INVALID") == 0) {
  // log for manual investigation
}
?>

Thanks!

Thank you, Soma for your help. It's working now. The code you gave me, helped me. I just added the the following:

<?php
if($p->numChildren){

foreach($page->get($p->name) as $fo){
		if(count($fo->get($fo->name))){
		   foreach($fo->get($fo->name) as $f1){
			  $fielddata->import($f1);
		   }
		}
	 }
} else {
  foreach($page->get($p->name) as $fo){
   $fielddata->import($fo);
}

FROM YOUR CODE

then how about like this?

function Pagefields(Page $page){  

$fielddata = new PageArray();

foreach($page->uses as $p){
	foreach($page->get($p->name) as $fo){
		if(count($fo->get($fo->name))){
			foreach($fo->get($fo->name) as $f1){
				$fielddata->import($f1);
			}
		}
	}
}
return $fielddata;
}

foreach(Pagefields($page) as $p){
echo "<p>$p->title</p>";
}

.... edited code a little.

MY FINAL VERSION

<?php

function Pagefields(Page $page){

 $fielddata = new PageArray(); // Nice !

 foreach ($page->uses as $p){

  if($p->numChildren){ // line added

	 foreach($page->get($p->name) as $fo){
		if(count($fo->get($fo->name))){
		   foreach($fo->get($fo->name) as $f1){
			  $fielddata->import($f1);
		   }
		}
	 }

  } else { // lined added
	 foreach($page->get($p->name) as $fo){
		$fielddata->import($fo);
	 }
  }

  } #endof: foreach($page->uses as $p){}

 return $fielddata; // Return me some data!
}

foreach(Pagefields($page) as $p){
 echo "<p>$p->title</p>"; // Yes, I got data!
}

Thank you again for your big help. Awesome Community!

Yes, you are correct I had to use strtolower($fo->title) for it to match or it will not work. $fielddata needs to returned data in each foreach loop.

then how about like this?

function Pagefields(Page $page){  

$fielddata = new PageArray();

foreach($page->uses as $p){
	foreach($page->get($p->name) as $fo){
		if(count($fo->get($fo->name))){
			foreach($fo->get($fo->name) as $f1){
				$fielddata->import($f1);
			}
		}
	}
}
return $fielddata;
}

foreach(Pagefields($page) as $p){
echo "<p>$p->title</p>";
}

.... edited code a little.

My code

<?php

function Pagefields(Page $page){

 $fielddata = new PageArray();

  foreach($page->uses as $p){

  //var_dump($p->title); // OUTPUTS. instances and categories

  foreach($page->get($p->name) as $fo){
	 //var_dump($fo->title); // OUTPUTS. Categories and 2D

	 // I need to $fielddata also in this foreach loop, so it returns (categories) in this page.
	 // Or, it will not return [2D] as the selected item in categories.
	 // But is not returning
	 $fielddata->import($fo);

	 // I changed the name to match with (categories) it was category before. So, I do not use strtolower($fo->title) function.
	 if(count($fo->get($fo->name))){
		foreach($fo->get($fo->name) as $f1){
		   var_dump($f1->title); // Yes, It outputs. Blender (software), CSS 3, HTML 5, Design, Development, 2D, 3D, Vehicle Design. No errors if I add another instance in (instances).
		   $fielddata->import($f1);
		}
	 }
  }
  } #endof: foreach($page->uses as $p){}

 return $fielddata;
}

foreach(Pagefields($page) as $p){
 //echo "<p>$p->title</p>";
 //var_dump($p->title);
}

Thank you for helping me.

EDIT : Attached file Pic #1 Pagefields > has 2 children assets and instances, it has 2 children categories and tags. Instances Page holds Categories and Tags, as you can see in Attached file # 1 if one of them matches I will get its data. Attached file Pic #1

And if you do?

if(count($page->instances)){
foreach($page->instances as $instance) {
	foreach($instance->categories as $cat){
		echo $cat->title;
	}
}
} else if($page->instances->categories){
  foreach($page->instances->categories as $cat) {
   echo $cat->title;
  }
} else {
echo "no instances";
}

Yes, that works for the first loop foreach($page->instances as $instance) {} it OUTPUTS. Blender (software), CSS 3, HTML 5, Design, Development, 2D, 3D, Vehicle Design. See the attached file # 3

EDIT : It does not work in foreach($instance->categories as $cat){ } if I add another instance in (instances). I have Categories, and Tags

It does not work. I get Warning: Invalid argument supplied for foreach()

<?php
foreach($page->instances->categories as $cat) {
  echo $cat->title;
}

It will be easy to change field name for every particular project. If I do not like the field name (instances) I can change to (references), something like that. The "Select Instance" field has to be in a foreach I have more (instances) in that list. For example: Categories, and Tags.

The [uses] field helps me not to hard-code the fields name in my page, so I can change the name of field on the fly, its more dynamic. It prevents me from opening an IDE.

Hello Community,

SETUP:

Fields I have (uses:Page), (instances:Page) and (categories:Page). Please see the attached file.

[ uses ] Selection of fields to render. See the attached file # 2

[ instances ] "Default" data for pages. See the attached file # 2

[ categories ] A bunch of items

CODE:

Renders the selected field from [ uses ] to the template. It's a simple way of not hard-coding the fields in your page. NOTE: Pagefields() is a function inside /site/templates/home.php

ISSUE:

I do not know how to exclude the parent's field ($fo->title) from field ($page->instances) (Categories). Which is foreach($page->{strtolower($p->title)} as $fo){} thus returning $fielddata. I want to get only the titles from ($fo->categories) and not the (Categories) title. I hope I am making sence. See the attached file # 3.

Field (uses)

Example: I select a field called (categories) from [ uses ] it outputs the title "2D". For this to work the current page or template has to have that field from [uses] or it will not work. See the attached file # 2

<?php
function Pagefields(Page $page, Pages $pages, Fields $fields){  
  $fielddata = array();

  foreach($page->uses as $p){

  var_dump($p->title); // OUTPUTS. instances, categories

  foreach($page->{strtolower($p->title)} as $fo){
	 $fieldr = strtolower($fo->title);

	 var_dump($fo->title); // OUTPUTS. Categories, 2D

	 $fielddata[] = $fo; // Returns the title (Categories) which I don't want. I do need to return the titles inside Categories with a field called (categories).

	 if($page->get($fieldr)!=NULL){
		foreach($fo->{$fieldr} as $f1){
		   $fielddata[] = $f1;
		   var_dump($f1->title); // OUTPUTS. Blender (software), CSS 3, HTML 5, Design, Development, 2D, 3D, Vehicle Design. See the attached file # 3
		}
	 }#endof: if($page->get($fieldr)!=NULL){}
  }

  } #endof: foreach($page->uses as $p){}

  return (object) $fielddata;
}

foreach(Pagefields($page, $pages, $fields) as $p){
  var_dump($p->title);
}

HARD-CODED VERSION: This is the other way of doing my code above. I do not want to hard-code the field names in my home.php file

I have debug set to TRUE and I get the following error.

<?php
foreach($page->instances as $p){
  foreach($p->categories as $cat){
  var_dump($cat->title); // OUTPUTS. Blender (software), CSS 3, HTML 5, Design, Development, 2D, 3D, Vehicle Design. See the attached file # 3
  }
}

## Warning: Invalid argument supplied for foreach() in line 2 foreach($p->categories as $cat){}

Thank you, Ryan!

Hi, Ryan

It works perfectly!

<?php

// 
foreach($page->assets as $inc) {  
        if(count($inc->fileimages)) foreach($inc->fileimages as $f) echo $f->basename . '<br />'; // prints project_01.png, project_02.png
}

Thank you, Ryan for the help!

Hi,

I am using ProcessWire 2.0.

Yes, I have populated the field "fileimages" and its lowercase.

I attached 2 files, so you can see my structure for my website.

<?php

// Code below works great! if I want the first image. I need all images attached.

foreach ($page->assets as $inc) {  
  if(count($inc->fileimages)){
echo $inc->fileimages->first()->basename; // prints project_01.png
  }
}
?>

Hi, Ryan

Thank you for your response. [Maximum files allowed] for "fileimages" is set to 0 for no limit.

I change the "max number of files" and I got an error: Notice: Trying to get property of non-object in D:\production\websites\processwire\site\templates\page.php

Hello, PW Community

I have 2 fields, one called "fileimages" typeof [image], second field is called "assets" typeof [Page].

The field "assets" contains the children of "Static" Page, please see structure below.

Home

|- Static

|- test_01

|- test_02

Setup > Fields

|- fileimages // typeof Image

|- assets // typeof Page # Containing the data of "Static" from above

Setup > Templates

|- page // Contains "assets"

<?php
// site/templates/page.php
foreach ($page->assets as $inc) {
  echo $inc->title // prints test_01, test_02
  echo $inc->fileimages->basename; // Getting no value
}
?>

The issue is that I cannot access a field inside of another field which contains data. # $inc->fileimages->basename.

Great community! Thanks to Ryan for this awesome Framework!
