Inline datetime pickers?

  Hey there,

  Is it possible to inline the jQuery UI datetimepicker so it doesn’t render as a popup? I’m loading a custom js file that updates the arguments (based off some other posts I found), but I can’t seem to do it. This is all backend on an options page BTW.

  Current code is:

  
  function extend(destination, source) {
  	for (var property in source)
  		destination[property] = source[property];
  	return destination;
  }
  
  acf.add_filter('date_time_picker_args', function( args, $field ){
  	
  	
  	var custom_args = {
          altField: $field,
  	};
      
  	args = extend(args, custom_args)
  	
  	return args;
  			
  });
  

  Based off the docs here: https://trentrichardson.com/examples/timepicker/ one of the demos has the datetimepicker altField set to put it inline.

  Like this:

  
  $('#alt_example_4').datetimepicker({
  	altField: "#alt_example_4_alt",
  	altFieldTimeOnly: false
  });
  

  Anyone have any ideas?

  OK, I’m going to answer my own question. It took a little time, but you can do it. For now, I’ve edited the core files, but will make my own ACF field to not interfere with the base datetimepicker.

  Two things to know:
  1. The datetimepicker is an extension of the jQuery UI date picker. It has a known bug that will NOT allow the time to be set in inline mode. However, I have a fix for that.
  2. To activate inline mode, you need to target a <div> or <span> as the target for the datetimepicker instead of the <input> tag.

  So, step one is to update the render_field method in the acf_field_date_and_time_picker.php file and class.

  Just to keep to the style of the existing code, I inserted a new DIV using the acf methods here:

  
  		$text_input = array(
  			'class' 				=> 'input',
  			'value'					=> $display_value,
  		);
  
  		$inline_calendar = array(
  			'class'					=> 'calendar-inline input'
  		);
  		
  		
  		// html
  		?>
  		<div <?php acf_esc_attr_e( $div ); ?>>
  			<?php acf_hidden_input( $hidden_input ); ?>
  			<?php // acf_text_input( $text_input ); ?>
  			<div <?php acf_esc_attr_e( $inline_calendar ); ?>></div>
  		</div>
  		<?php
  		
  	}
  

  This will insert the div below the text input, and comment out the text input.

  Next, update the acf-input.js file to edit the javascript of the picker.

  Note that the datetimepicker is an extension of the date picker. So, around line 5811 there will be a definition for the date_picker and it will declare the $inputText.

  
  		$inputText: function(){
  			return this.$('.calendar-inline');
  			// return this.$('input[type="text"]');
  		},
  

  This should now return your .calendar-inline class instead of the <input> tag.

  Lastly, a bit further down, in the date_time_picker section (not date_picker section) there is a declaration to add.newDateTimePicker on line 6031. We need to update that to update the calendar with the current time.

  
  	// add
  	acf.newDateTimePicker = function( $input, args ){
  		
  		// bail ealry if no datepicker library
  		if( typeof $.timepicker === 'undefined' ) {
  			return false;
  		}
  		
  		// defaults
  		args = args || {};
  		
  		// NEW - Remember date/time
  		$date = args.altField[0].value;
  
  		// initialize (This wipes the datetime in inline mode)
  		$picker = $input.datetimepicker( args );
  
  		// update to current datetime with the value 2 lines above.
  		$picker.datetimepicker('setDate', (new Date($date)) );
  		
  		// wrap the datepicker (only if it hasn't already been wrapped)
  		if( $('body > #ui-datepicker-div').exists() ) {
  			$('body > #ui-datepicker-div').wrap('<div class="acf-ui-datepicker" />');
  		}
  	};
  

  We effectively store the datetime before we initialise the datetimepicker and then update it once it’s created.

  Now you should have an embedded calendar.

  Couple of gotchas:
  1. Remember to hard-reload and clear cache to reload the new JS.
  2. The acf-input.min.js gets loaded by default, you can test the acf-input.js by updating the /includes/assets.php file and the enqueue_script location OR just define the constant SCRIPT_DEBUG to use the non-minified version.

  OK, I created a new ACF-Field for it.

  First ACF plugin, so be nice!
