Accessing the value of different fields inside a repeater

I've been trying to figure a way to output the values of several fields within a single repeater using a foreach() without having to reference the name of the fields.

Typically, for repeaters, I understand you would do foreach($repeater_field as $afield) { echo $afield->fieldname_a; } pretty straight forward.

Anyways, what I'm doing is using a single repeater as just a container for other fields.

I've tried using $page->my_repeater->getArray(), then looping through the array, and all sorts of methods, without luck. It seems I must specify the field name for output.

For instance, my (single) repeater is set up to hold a few different fields:

my_repeater

  • field_a
  • field_b
  • field_c

Trying to output it using something like this:

foreach($page->my_repeater as $afield) {

     echo $afield->value;   // I'm not wanting to have the reference the field name e.g. use $afield->field_a

}

 

Any suggestions?

Something like this maybe?

<?php

// get all field names
$fieldNames = $page->repeater_field->first->fields->explode('name');
// get all content from all fields
$content = $page->repeater_field->explode($fieldNames);

// array comes out multidimensional unfortunately

// iterate recursively
// https://stackoverflow.com/questions/1319903/how-to-flatten-a-multidimensional-array
$iter = new \RecursiveIteratorIterator(new \RecursiveArrayIterator($content));
// and print all content
foreach($iter as $part) {
    echo $part;
}

This works in my setup.

I think perhaps I am not understanding what you are looking for, but does this suit your needs?

foreach($page->my_repeater as $item) {
    foreach($item->fields as $field) {
        echo $item->{$field->name};
    }
}

Exactly what I was looking for. That worked  @adrian

You provided a great solution that works.

I would have never thought of $item->{$field->name} as storing the value of the field.

The way I was originally thinking, in pseudocode was something like:

$all-repeater-fields = $page->my_repeater->getchildren();

foreach($all-repeater-fields as $a-field) {

echo $a-field->name;

echo $a-field->value;

}

Could you also guide me into a direction in the PW docs or method in which you came across this?  It seems little things like this, I dig into the documentation and API reference, and just can't find good examples/explanations for these types of questions. I try using var_dump() and the docs to try to 'connect' the dots, but something with the way I'm researching just isn't 'clicking'. The idea of $item->{$field->name} holding the value for the field would have never crossed my mind.

Thanks so much for the assistance --

Glad it worked for you :)

Remember that $field->name is going to refer to things like "body", "headline", etc so it's actually calling: $item->body which returns the value of the body field. 

The use of $item->fields is like $page->fields which is mentioned in the docs and cheatsheet.

Shameless plug, but I really find the Console panel in Tracy Debugger an incredibly useful tool - it lets you try code and dump objects and arrays in a nicely formatted way - it really helps the learning process.

      Repeater Easy Sort
      Adds a compact "easy-sort" mode to Repeater and Repeater Matrix, making those fields easier to sort when there are a large number of items.
      The module also enhances Repeater Matrix by allowing a colour to be set for each matrix type. This colour is used in the item headers and in the "add new" links, to help visually distinguish different matrix types in the inputfield.
      Screencasts
      A Repeater field

      A Repeater Matrix field with custom header colours

      Easy-sort mode
      Each Repeater/Matrix item gets an double-arrow icon in the item header. Click this icon to enter easy-sort mode.
      While in easy-sort mode:
      The items will reduce in width so that more items can be shown on the screen at once. The minimum width is configurable in the field settings. Any items that were in an open state are collapsed, but when you exit easy-sort mode the previously open items will be reopened. You can drag an item left/right/up/down to sort it within the items. The item that you clicked the icon for is shown with a black background. This makes it easier to find the item you want to move in easy-sort mode. You can click an item header to open the item. An "Exit easy-sort mode" button appears at the bottom of the inputfield. Configuration
      In the field settings for Repeater and Repeater Matrix fields you can define a minimum width in pixels for items in easy-sort mode. While in easy-sort mode the items will be sized to neatly fill the available width on any screen size but will never be narrower than the width you set here.
      In the field settings for Repeater Matrix you can define a custom header colour for each matrix type using an HTML "color" type input. The default colour for this type of input is black, so when black is selected in the input it means that no custom colour will be applied to the header.
      Exclusions
      The easy-sort mode is only possible on Repeater/Matrix fields that do not use the "item depth" option.

      Long time user and huge fan of PW, but this time I can't find an answer to my question this time:
      For my social media buttons, I have a Repeater field called var_link_web with two fields: one is for the URL, and the other is an Images field containing two images that are used as a background-image for a <div>, of which the second is the ':hover' version (although activated through JavaScript here). 
      There are four instances of this Repeater, of which two are 'turned off'.
      I use the following PHP in my _main.php to call them, wrapped in <p><?php == ?></p>:
      $s_m_button = $variables->var_link_web; foreach($s_m_button as $button){ $button_image = $button->var_link_image->first->height(80); $button_image2 = $button->var_link_image->eq(1)->height(80); echo " <a href='$button->var_link_url'> <div class='image_link' style='background-image:url({$button_image->url})' onMouseOver='this.style.backgroundImage=url({$button_image2->url})' onMouseOut='this.style.backgroundImage=url({$button_image->url})'> </div> </a>"; }; ($variables leads to an unpublished page with several fields I want to have easy access to, and is defined in _init.php.)
      However, this gives me the following result:

      I have no idea where the extra <p>'s come from. The URL field has the 'HTML Entity Encoder' turned on. What's even weirder is that the HTML source file seemingly renders correctly:
      <p> <a href='https://www.facebook.com/'> <div class='image_link' style='background-image:url(/site/assets/files/1045/icons-facebook-square.0x80.png)' onMouseOver='this.style.backgroundImage="url(/site/assets/files/1045/icons-facebook-square2.0x80.png)"' onMouseOut='this.style.backgroundImage="url(/site/assets/files/1045/icons-facebook-square.0x80.png)"'> </div> </a> <a href='https://www.instagram.com/'> <div class='image_link' style='background-image:url(/site/assets/files/1046/icons-instagram-square.0x80.png)' onMouseOver='this.style.backgroundImage="url(/site/assets/files/1046/icons-instagram-square2.0x80.png)"' onMouseOut='this.style.backgroundImage="url(/site/assets/files/1046/icons-instagram-square.0x80.png)"'> </div> </a> </p> Removing the JavaScript has no effect. I'm probably missing something obvious, but am at a loss here.
       
      Thank you in advance!

      Hi,
      I'm facing the issue where i have a repeater field with a multi language textarea (german & english, german beeing default). In german more blocks should be displayed as in english.
      The textarea field is configured as inherit default language if blank (I don't want to change this since it is the wanted behaviour for all other pages...).
      Now I want to access the unformatted value of the textarea field in the repeater and only show it if it is not empty. Something like this:
      $body = ""; $page->of(false); foreach($page->blocks as $block){ //blocks is repeater field, each block has title and textarea if ($block->textarea->getLanguageValue($user->language)){ $body .= <<<EOD <div> <div class='uk-card uk-card-default uk-card-body'> <h3 class='uk-card-title'>$block->title</h3> $block->textarea </div> </div> EOD; } } $page->of(true); print $body; However this doesn't work: Call to a member function getLanguageValue() on string.
      I also tried the other syntax for getLanguageValue:
      $page->getLanguageValue($language, $field) But I didn't manage to get a unique name of the textarea field in the repeater.
      I looked into the API of FieltypeRepeater but couldn't find anyhting that fixed my issue.
      Any ideas?

      Hi all,
      I could have sworn I used to be able to use the site generic 'title' field as a sub field of a repeater field. However I've tried to do this on two 3.0.165 sites recently and, while it will add the title field in the repeater field setup, it wont save the repeater title sub field's content when the repeater is used in a page template and edited.
      It;'s not a big issue but I wondered if this was a known restriction?

      I see old posts saying that repeaters are not the way to go in Custom Process Modules. If that is the case, when using forms (as I am trying to do) how would one tackle things like repeat contact fields where there can be multiple requirements for contact details with different parameters? (Like point of contact, director, etc) or even telephone numbers that have different uses?
      Just for background I am creating a process module that allows me to create types of financial applications in the admin area (no need to publish any of this, pure admin) that require a lot of personal or company information.
      Maybe I am thinking about this incorrectly?
