drupal menu hook -- how to add formatting - drupal-6

I want to add some additional formatting to my menu. I've been looking at menu.inc and am unsure which method would i override to do something like the following.
if content type = "fund"
print " some additional formatting "

That's not really something you would want to do in the hook_menu, actually.
I'm not sure what you're doing for sure, but it sounds like what you want to do is to use the hook_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) hook, something like this:
function example_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
if ($op == 'view' && $node->type == 'fund') {
$node->content['my_fund_data'] = array(
'#value' => 'Some additional formatting',
'#weight' => 10,
);
}
}
Now, if what you want to do is change the content instead of just add something below it, you'll want to investigate what the rendered node looks like - I suggest installing the devel module, which will give you a link to view the rendered node data easily.

How do I make puppeteer wait for element to load (in a loop)?

I am trying to use puppeteer in order to fill in a form and get the results.
when the form is submitted correctly, a table containing the results appear which has #some_id. Now I'm looking for a good way to wait until the table is loaded and if the code fails, redo the process of filling in the form until it works correctly. I want it to do something like this (pseudo code):
while(table_is_not_loaded){
get_information;
fill_in_the_form;
submit_the_form;
}
I think that it's maybe achievable using page.waitForSelector() function, but I can't use it the way I want and I also don't know how it handle errors if the selector is not ready or visible.
You could do something like this:
let table_is_loaded = true;
await page.waitForSelector('someID').catch(e => table_is_loaded = false);
while(!table_is_loaded){
get_information;
fill_in_the_form;
submit_the_form;
table_is_loaded = true;
await page.waitForSelector('someID').catch(e => table_is_loaded = false);
}
Maybe something like:
while(true){
try {
await page.waitForSelector('#foo')
get_information;
fill_in_the_form;
submit_the_form;
break
} catch(e) {
}
}
after some searching and trying different pieces of code , i came to a solution and it was using the.$eval() method to access html attributes and checking the height of the element( you could also check other things as well like display or visibility )
const isNotHidden = await mainPage.$eval(
"#some_id",
elem => {
return (
window.getComputedStyle(elem).getPropertyValue("height") >= "5px"
);
}
);

Knockout Binding with Multiple If statements

I am applying binding on a style and have succeeded in making the background colour change based on two scenarios. At present it says if the status is 'START', make the background #d10000, else make the background #93d667.
style: { background: ManagerStatus() == 'START' ? '#d10000' : '#93d667' }
I would like the following functionality:
If START, make #d10000
else if CONTINUE, make #93d667
else make #f7f7f7
How do I achieve these multiple case statements in Knockout binding?
Regards
Alexandra
Thanks guys. For future reference someone showed me that you can actually have multiple cases in the data-bind attribute:
{background: ManagerStatus() == 'START' ? '#d100000' : (ManagerStatus() == 'CONTINUE' ? '#93d667' : '#f7f7f7')}

You avoid filling your html with conditional logic and create a knockout computed observable in your viewmodel like so:
// or however your viewModel is currently set up.
var viewModel = {
ManagerStatus: ko.observable()
}
viewModel.statusBackground = ko.computed(function() {
status = this.ManagerStatus(),
switch (status) {
case "START": return "#d10000";
case "CONTINUE": return "#93d667";
default: return #f7f7f7;
}
}, viewModel);
html
style: { background: statusBackground }
You could do it by nesting two ternary operator expressions. But doing so it's not a good idea: it's much better to modify your View Model, and include a computed observable that returns the backgraound color. Something like this:
var vm = function() {
var self = this;
self.ManagerStatus = ko.observable();
self.backgroundcolor = ko.computed(function() {
ManagerStatus() == 'START'
? '#d10000' : ManagerStatus() == 'CONTINUE'
? '#93d667' : '#f7f7f7';
});
return self;
};
The binding would be like this:
style: { background: backgroundcolor }
Note that you in this case can use a pure computed, instead of a regular computed.
NOTE: I've shown how to write a nested ternary operator, and you could include it in the binding expression. But, if it looks ugly in a view model definition, it's even more ugly in a binding expression. In fact, I wouldn't write it like this in the view model definition. Much better to use chained if else or switch to make it more readable.

recognize multple lines on info.selectionText from Context Menu

My extension adds a context menu whenever a user selects some text on the page.
Then, using info.selectionText, I use the selected text on a function executed whenever the user selects one of the items from my context menu. (from http://code.google.com/chrome/extensions/contextMenus.html)
So far, all works ok.
Now, I got this cool request from one of the extension users, to execute that same function once per line of the selected text.
A user would select, for example, 3 lines of text, and my function would be called 3 times, once per line, with the corresponding line of text.
I haven't been able to split the info.selectionText so far, in order to recognize each line...
info.selectionText returns a single line of text, and could not find a way to split it.
Anyone knows if there's a way to do so? is there any "hidden" character to use for the split?
Thanks in advance... in case you're interested, here's the link to the extension
https://chrome.google.com/webstore/detail/aagminaekdpcfimcbhknlgjmpnnnmooo
Ok, as OnClickData's selectionText is only ever going to be text you'll never be able to do it using this approach.
What I would do then is inject a content script into each page and use something similar to the below example (as inspired by reading this SO post - get selected text's html in div)
You could still use the context menu OnClickData hook like you do now but when you receive it instead of reading selectionText you use the event notification to then trigger your context script to read the selection using x.Selector.getSelected() instead. That should give you what you want. The text stays selected in your extension after using the context menu so you should have no problem reading the selected text.
if (!window.x) {
x = {};
}
// https://stackoverflow.com/questions/5669448/get-selected-texts-html-in-div
x.Selector = {};
x.Selector.getSelected = function() {
var html = "";
if (typeof window.getSelection != "undefined") {
var sel = window.getSelection();
if (sel.rangeCount) {
var container = document.createElement("div");
for (var i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
html = container.innerHTML;
}
} else if (typeof document.selection != "undefined") {
if (document.selection.type == "Text") {
html = document.selection.createRange().htmlText;
}
}
return html;
}
$(document).ready(function() {
$(document).bind("mouseup", function() {
var mytext = x.Selector.getSelected();
alert(mytext);
console.log(mytext);
});
});​

How to add custom blocks in drupal?

I have a simple module which will return a form , but now i have added this to a menu like
admin/settings/
But i want this form in another page ,so i added a hook_block() , my module showed up in the blocks page and i added it to be seen by all in all pages in content area but i dont get that form ? where did i go wrong ? I am new to drupal any help plz
function emp_form_block($op = 'list', $delta = 0, $edit = array()) {
switch ($op) {
case 'list':
$blocks[0]['info'] = t('New Block');
$blocks[0]['cache'] = BLOCK_NO_CACHE;
return $blocks;
}
}
i am using drupal 6
You should also implement the view op, like this:
case 'view':
return array(
'subject' => t('My awesome form'),
'content' => drupal_get_form('my_awesome_form'),
);
break;

Drupal 6: Working with Hidden Fields

I am working on an issue i'm having with hooking a field, setting the default value, and making it hidden. The problem is that it is taking the default value, but only submitting the first character of the value to the database.
//Here is how I'm doing it
$form['field_sr_account'] = array( '#type' => 'hidden', '#value' => '45');
I suppose there is something wrong with the way that I have structured my array, but I can't seem to get it. I found a post, http://drupal.org/node/59660 , where someone found a solution to only the first character being submitted
//Here is the format of the solution to the post - but it's not hidden
$form['field_sr_account'][0]['#default_value']['value'] = '45';
How can I add the hidden attribute to this?
Have you tried using #default_value insted of #value?
Also if you're trying to pass some data to the submit that will not be changed in the form you should use http://api.drupal.org/api/drupal/developer--topics--forms_api_reference.html#value .
The answer was actually to set the value and the hidden attribute separately, then set the value again in the submit handler using the following format.
I'm not sure if it's all necessary, I suppose I probably don't need to assign it in the form alter, but it works, so I'm going to leave it alone...
$form['#field_sr_account'] = $club;
$form['field_sr_account'] = array( '#type' => 'hidden','#value' => $club);
}
}
/*in submit handler, restore the value in the proper format*/
$form_state['values']['field_sr_account'] = array('0' => array('value' => $form['#field_sr_account']));
An interesting solution from http://drupal.org/node/257431#comment-2057358
CCK Hidden Fields
/**
* Implementation of hook_form_alter().
*/
function YourModuleName_form_alter(&$form, $form_state, $form_id) {
if (isset($form['type']) && isset($form['#node'])) {
### Make a CCK field becoming a hidden type field.
// ### Use this check to match node edit form for a particular content type.
if ($form_id === 'YourContentTypeName_node_form') {
$form['#after_build'] = array('_test_set_cck_field_to_hidden');
}
}
}
function _test_set_cck_field_to_hidden($form, &$form_state) {
$form['field_NameToBeHidden'][0]['value']['#type'] = 'hidden';
$form['field_NameToBeHidden'][0]['#value']['value'] = 'testValue';
return $form;
}
