Concrete5 – Form styling

Concrete5 bietet einen netten Form Block, mit dem man Formulare in wenigen Sekunden erstellen. Dies ohne HTML oder PHP Kenntnisse. Unglücklicherweise lässt sich der HTML Code davon, nur schlecht mit CSS anpassen. In diesem Tutorial zeige ich, wie man ein Formular in diesem Stil erstellen kann:

Styles Form

Custom Templates

Das Stichwort “Custom Templates” sollte bekannt sein, ansonsten bitte zuerst diesen Artikel durchlesen: http://www.codeblog.ch/2009/03/concrete5-templates/. Kurz zusammengefasst: Concrete5 erlaubt es, mittels “Custom Templates” sämtliche Blöcke in ihrem Erscheinungsbild anzupassen, falls mit CSS nicht genügend Möglichkeiten zur Verfügung stehen sollten.

Core Änderungen

Der Controller des Form Blocks hat eine kleine Unschönheit, welche das “stylen” mit CSS etwas erschwert. Da keine Funktionalität daran hängt, hab ich in diesem Fall den Code im “Core” direkt modifiziert. Ev. wird das in einer zukünftigen Version geändert. Es betrifft die Datei “concrete/blocks/form/controller.php” in der Zeile 667:

pic1

Die Anweisung ‘style=”width:95%”‘ ist zu entfernen.

Das Standard Layout

Wird ein Formular mit Concrete5 erstellt, sieht es standardmässig so aus:

pic3

Es funktioniert, sieht aber nicht wirklich hübsch aus.

Das neue Layout

In diesem Tutorial zeige ich, wie man ein Formular erstellen kann, bei dem die Labels nicht neben den Eingabefeldern stehen, sondern gleich im Feld. Dies kann besonders nützlich sein, wenn wenig Platz vorhanden ist, und ein grosses Formular einzufügen ist. Das PHP Template view.php

Ich werde nicht jede Zeile erklären, da dies etwas umfangreich wäre. Ich geh davon aus, dass PHP Kenntnisse vorhanden sind.
Kurz aufgelistet, was geändert wurde:

  • Einige Methoden vom Controller werden neu aus der View aufgerufen
  • Das Tabellen Layout durch DIV’s ersetzt
  • CSS Klassen eingefügt, welche für die JavaScript Checks verwendet werden
  • $_REQUEST angepasst, damit die Labels im “value” Attribute ausgegeben werden

Nun haben wir ein Formular, bei dem die Labels in den Eingabefeldern ausgegeben werden. Wir müssen nun aber auch sicherstellen, dass diese vordefinierten Werte ersettz werden können, ansonsten kann es passieren, dass Formulare mit diesen Werten abgeschickt werden können.
Dazu werden verschiedene Events geprüft:

1
2
3
   $('.miniSurveyView input[type=text], textarea').click(onEnterField);
   $('.miniSurveyView input[type=text], textarea').focus(onEnterField);
   $('.miniSurveyView input[type=text], textarea').blur(onLeaveField);

Sobald ein Benutzer ein Feld aktiviert oder verlässt, werden diese Funktionen aufgerufen. Dort wird geprüft, ob der Wert zu ersetzen ist oder nicht:

1
2
3
4
5
6
7
8
9
10
11
12
function onEnterField() {
   if (this.origLabel == null)
      this.origLabel = this.value;
   if (this.origLabel == null || this.origLabel == this.value)
      this.value = '';
 
	$(this).prev(".formError").slideUp();
}
function onLeaveField() {	
   if (this.value == '' && this.origLabel != null)
      this.value = this.origLabel;
}

Zusätzlich kommen ein paar clientseitige Checks dazu, um dem Benutzer sofort einen Hinweis betreffend nicht ausgefüllten Feldern ausgeben zu können.

$(document).ready(function() {
 
   $('.miniSurveyView input[type=text], textarea').click(onEnterField);
   $('.miniSurveyView input[type=text], textarea').focus(onEnterField);
   $('.miniSurveyView input[type=text], textarea').blur(onLeaveField);
 
	$('.miniSurveyView').submit(function() {
		var formErrors = 0;
 
		$('.formError').remove();
		$('input[type=text], textarea', this).each(function() {
 
			if (($(this).attr('origLabel') == undefined || $(this).val() == $(this).attr('origLabel')) && $(this).parent().hasClass("required")) {
				formErrors++;
				$(this).before('
<div class="formError" id="formError'+formErrors+'" style="height:18px;color:red;font-size:10px;display:none;">Bitte Wert eingeben:</div>
')
				$("#formError" + formErrors).slideDown(200,function() {					
				});
			}
		})
 
		if (formErrors > 0)
			return false;
		else
			return true;
	})
 
});

Wir in einem Feld kein Wert eingegeben, wird ganz einfach oberhalb davon eine entsprechende Meldung ausgegeben.

Das Template enthält einige CSS Anweisungen, welche ich hier nicht weiter erkläre. Mit grundlegenden CSS Kenntnissen sind diese problemlos zu verstehen und können auch entsprechend angepasst/erweitert werden. Sämtliche Dateien finden sich in folgendem ZIP:

Template herunterladen

Den Inhalt der ZIP Datei ins Verzeichnis “blocks/form/templates” entpacken. Die Verzeichnisse “form” und “templates” müssen ev. vorgängig erstellt werden!
Viel Spass!

    Thanks Remo – this is so helpful. As always!

    The send button reads “senden” which I changed to English “Send” in view.php, line 66

    Also there was some German in the view.js file, line 29. I changed this to English “Please enter a value” .

    Is that OK?

    $(this).before(‘Bitte Wert eingeben:’)

  • Remo Laubacher

    Yes of course. I should have made those “translatable” but since block translations aren’t well supported in Concrete5 I tend to use the language I need without using gettext..

  • dekelly

    Hi Remo,

    The drop down list selector doesnt display properly – the field title disappears and the width is not justified with the other fields. How do I fix this?

  • Remo Laubacher

    This is most likely a css issue. I think I missed the “select” element. When you look at the css you see a rule which starts like this:
    .ccm-form-element input {

    Modify it to:
    .ccm-form-element input, .ccm-form-element select {

    I haven’t tested it – send me a link if it doesn’t work.

  • dekelly

    Hi Remo,

    Thanks for your responses.

    I modified the css as you specified above. The url is;

    http://www.espmasia.com/index,php/en/people/careers

    3 issues;

    1. The title for the Attachment field and Expertise drop down menu are not displaying.

    2. Input id= > validator says there is no value specified

    3. ampersand issue highlighted by validator

    INPUT ID ISSUE
    For the div corresponding to the field to browse for and attach a form, the validator highlighted:

    143 E622 The ‘id’ attribute does not have a valid value: It does not contain a valid ID. It must begin with a letter, underscore or colon and may be followed by any number of letters, digits [0-9], hyphens,underscores, colons, and periods:

    143

    Firebug confirms:

    What should this “input id” be and where do I write it?

    AMPERSAND ISSUE (on last line of snippet)

    139 E007 Found ‘&’ within ‘action’. You should use ‘&’ instead:

    I looked in all the associated “view” files but couldnt find where this “&” is coming from.

    I’m not very familiar with php and search and trawl forums for quite a while before I resort to asking you so I appreciate your patience. I’ll post your solutions in the W3C Valid thread on the C5 bug tracker forum (http://www.concrete5.org/index.php?cID=1473)

  • dekelly

    For some reason the complete code that I copy/pasted is not displaying. (also other posts) You’ll see when you run the validator on the page

  • Remo Laubacher

    1. see comment above, you need to add some more css rules
    2. not sure, have to check this
    3. this isn’t related to template but has been fixed a while ago as far as I know. Are you using the latest c5 version?

  • Ryan Mcfarlane

    Anyone managed to get this to direct the user to a new page when they complete the form?

    Big thanks for this posting, just set it up and it looks great!

  • Ryan Mcfarlane

    Cant seem to get this to install on the latest version of C5, any ideas of a work around?

  • Riadh Jouili

    hey Eyan,

    don´t erase ’style=”width:95%”‘ just change it to ’style=”none”‘ and it will work with the latest version!

  • Janne Kurkinen

    Nice tutorial!

    I’m having problems with error checking. I modified the submit button to be replaced with a custom imaged anchor:

    echo ‘
    Ilmoittaudu!‘;

    The button works fine, but submits without error checking, showing thank you message after each submit. If I try with the original button, the error checking JS doesn’t work anyway. Otherwise inputfield scripts work fine!

    Would anyone have a thought where to spot this bug?

  • andio

    in function onLeaveField() the last line has to be

    this.origLabel = null;

    otherwise it will only work once.

    Great work done! Keep that going on :)

  • Janne Kurkinen

    Hi again!

    Why Im I having these problem with error checking?

    With the original JS it founds no erros ever.

    If I replace “this.origLabel = null;” in function onLeaveField() with
    “this.value = this.origLabel; ” clear field upon click only once. So if I don’t click them, it founds to errors with them. And also if it founds errors, the fields are cleared…

    If I just add “this.origLabel = null;” after “this.value = this.origLabel; ” I found no change in the workings.

    Sorry. I’m no coder with JS… But it seems this code is nowhere near complete, or for some reason it works differently for me as I modified the submit work by:
    onclick=”this.blur(); document.getElementById(‘. “‘miniSurveyView”.intval($bID).”‘”.’).submit();

  • klospo

    Thanks o lot for this !!! A real timesaver.

    One Question: Should it work in IE6 ?
    Every text field is working except for the Captcha input form.
    Or is there any other Problem with my Html/Css?

    thanks again, greets

  • Remo Laubacher

    I can’t see any reasons why there should be an IE6 specific issue but I only have a browser museum at work. Do you get any error messages? I’m sure we can fix that if you could post a few more details at http://www.concrete5.ch

  • klospo

    thanx for your reply. I´ll try to figure this out. There aren´t any error messages, it isn´t clickable, you can´t write in this field. Perhaps theres a problem with my css? I´ll write the solution in this place or the more details if i cant fix it at concrete5.ch.
    Greets, thx

  • klospo

    Hello again, it was NO problem with this code. It was a weird problem with transparent png´s and js. Damn IE :-)

  • Remo Laubacher

    Why are you trying to call view.php directly? It’s a block template, you have to select it while you’re in the edit mode of the page where the form block can be found. Click on the block and select “Custom Template” and pick the new template from the list. I Concrete5 everything goes through index.php, you’re not supposed to open php file directly.

  • J

    The Javascript file doesn’t seem to work at all. I couldn’t even get an alert to call from within any of the functions. Also the first few if statements don’t have brackets around the function. Where does it go? I was also unable to get the CSS file to work until I moved it up one level out of the templates folder.

  • Remo Laubacher

    The JavaScript file looks fine to me. If you can’t even use an alert command to display a message there has to be a JavaScript error in the console! Please check that.
    Also, you don’t need to have any brackets if there’s just one line of command to execute.
    Did you see that there’s a link to download the complete code at the end of the article?

  • J

    Ok fixed everything from my old comment. Looks like the .css and .js files need to be put into a ‘CSS’ and ‘JS’ directory respectively within the blocks/form/templates/yourTemplate/

  • Tom

    Hi Remo,

    I have problems with your excellent template on new version of C5 (5.4.2.1. – jQuery Form plugin is updated to 2.82. ).
    Text fields do not recognize input (error: Bitte Wert eingeben:). E-mail field is OK (see attached web address).

    Thanks for the help in advance.

    Btw: Congs. on the book.

  • Remo Laubacher

    Hi Tom,
    I’m not sure about the code you’ve created, it seems that you’re using a HTML5 form type but don’t use the correct doctype.
    Also, why did you update the jQuery form plugin? The template I’ve created doesn’t use that plugin?!
    Thanks,
    Remo

  • Tom

    Hi,
    I’m sorry for misunderstandings.
    I was pointing out that version of jquery (2.82) is built in new installation of Concrete5 (5.4.2.x). On the test site (as you can see – with core page templates), your e-mail template is also ‘virgin’, without any modifications.
    Thanks for quick answers.
    Tom

  • Remo Laubacher

    I’m not really sure I can show a label for a drop down, have you seen any example where that works? I could display a completely different element on top of it but that would take quite a bit more time..
