  • What's the best way to pass a PHP variable to Javascript?

    - by Gregory Bolkenstijn
    I currently echo certain variables in hidden input fields and read them out with Javascript whenever I need them. Me and a colleague are now thinking of generating an extra Javascript file with PHP which only contains all variables for Javascript. This way the variables already exist and there is no extra code in the HTML. What are good ways to pass variables from PHP to Javascript? And how does our solution sound?

  • form_dropdown in codeigniter

    - by Patrick
    I'm getting a strange behaviour from form_dropdown - basically, when I reload the page after validation, the values are screwed up. this bit generates 3 drop downs with days, months and years: $days = array(0 => 'Day...'); for ($i = 1; $i <= 31; $i++) { $days[] = $i; } $months = array(0 => 'Month...', ); for ($i = 1; $i <= 12; $i++) { $months[] = $i; } $years = array(0 => 'Year...'); for ($i = 2010; $i <= 2012; $i++) { $years[$i] = $i; echo "<pre>"; print_r($years); echo "</pre>";//remove this } $selected_day = (isset($selected_day)) ? $selected_day : 0; $selected_month = (isset($selected_month)) ? $selected_month : 0; $selected_year = (isset($selected_year)) ? $selected_year : 0; echo "<p>"; echo form_label('Select date:', 'day', array('class' => 'left')); echo form_dropdown('day', $days, $selected_day, 'class="combosmall"'); echo form_dropdown('month', $months, $selected_month, 'class="combosmall"'); echo form_dropdown('year', $years, $selected_year, 'class="combosmall"'); echo "</p>"; ...and generates this: <p><label for="day" class="left">Select date:</label><select name="day" class="combosmall"> <option value="0" selected="selected">Day...</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> <option value="11">11</option> <option value="12">12</option> <option value="13">13</option> <option value="14">14</option> <option value="15">15</option> <option value="16">16</option> <option value="17">17</option> <option value="18">18</option> <option value="19">19</option> <option value="20">20</option> <option value="21">21</option> <option value="22">22</option> <option value="23">23</option> <option value="24">24</option> <option value="25">25</option> <option value="26">26</option> <option value="27">27</option> <option value="28">28</option> <option value="29">29</option> <option value="30">30</option> <option value="31">31</option> </select><select name="month" class="combosmall"> <option value="0" selected="selected">Month...</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> <option value="11">11</option> <option value="12">12</option> </select><select name="year" class="combosmall"> <option value="0" selected="selected">Year...</option> <option value="2010">2010</option> <option value="2011">2011</option> <option value="2012">2012</option> </select></p> however, when the form is reloaded after validation, the same code above generates this: <!-- days and months... --> <select name="year" class="combosmall"> <option value="0" selected="selected">Year...</option> <option value="1">2010</option> <option value="2">2011</option> <option value="3">2012</option> </select> So basically the value start from 1 instead of 2010. The same happens to days and months but obviously it doesn't make any difference in this particular case as the values would start from 1 anyway. How can I fix this - and why does it happen? edit: validation rules are: $this->load->library('form_validation'); //...rules for other fields.. $this->form_validation->set_rules('day', 'day', 'required|xss_clean'); $this->form_validation->set_rules('month', 'month', 'required|xss_clean'); $this->form_validation->set_rules('year', 'year', 'required|xss_clean'); $this->form_validation->set_error_delimiters('<p class="error">', '</p>'); //define other errors if($this->input->post('day') == 0 || $this->input->post('month') == 0 || $this->input->post('year') == 0) { $data['error'] = "Please check the date of your event."; }

  • T-SQL generated from LINQ to SQL is missing a where clause

    - by Jimmy W
    I have extended some functionality to a DataContext object (called "CodeLookupAccessDataContext") such that the object exposes some methods to return results of LINQ to SQL queries. Here are the methods I have defined: public List<CompositeSIDMap> lookupCompositeSIDMap(int regionId, int marketId) { var sidGroupId = CompositeSIDGroupMaps.Where(x => x.RegionID.Equals(regionId) && x.MarketID.Equals(marketId)) .Select(x => x.CompositeSIDGroup); IEnumerator<int> sidGroupIdEnum = sidGroupId.GetEnumerator(); if (sidGroupIdEnum.MoveNext()) return lookupCodeInfo<CompositeSIDMap, CompositeSIDMap>(x => x.CompositeSIDGroup.Equals(sidGroupIdEnum.Current), x => x); else return null; } private List<TResult> lookupCodeInfo<T, TResult>(Func<T, bool> compLambda, Func<T, TResult> selectLambda) where T : class { System.Data.Linq.Table<T> dataTable = this.GetTable<T>(); var codeQueryResult = dataTable.Where(compLambda) .Select(selectLambda); List<TResult> codeList = new List<TResult>(); foreach (TResult row in codeQueryResult) codeList.Add(row); return codeList; } CompositeSIDGroupMap and CompositeSIDMap are both tables in our database that are represented as objects in my DataContext object. I wrote the following code to call these methods and display the T-SQL generated after calling these methods: using (CodeLookupAccessDataContext codeLookup = new CodeLookupAccessDataContext()) { codeLookup.Log = Console.Out; List<CompositeSIDMap> compList = codeLookup.lookupCompositeSIDMap(5, 3); } I got the following results in my log after invoking this code: SELECT [t0].[CompositeSIDGroup] FROM [dbo].[CompositeSIDGroupMap] AS [t0] WHERE ([t0].[RegionID] = @p0) AND ([t0].[MarketID] = @p1) -- @p0: Input Int (Size = 0; Prec = 0; Scale = 0) [5] -- @p1: Input Int (Size = 0; Prec = 0; Scale = 0) [3] -- Context: SqlProvider(Sql2005) Model: AttributedMetaModel Build: 3.5.30729.1 SELECT [t0].[PK_CSM], [t0].[CompositeSIDGroup], [t0].[InputSID], [t0].[TargetSID], [t0].[StartOffset], [t0].[EndOffset], [t0].[Scale] FROM [dbo].[CompositeSIDMap] AS [t0] -- Context: SqlProvider(Sql2005) Model: AttributedMetaModel Build: 3.5.30729.1 The first T-SQL statement contains a where clause as specified and returns one column as expected. However, the second statement is missing a where clause and returns all columns, even though I did specify which rows I wanted to view and which columns were of interest. Why is the second T-SQL statement generated the way it is, and what should I do to ensure that I filter out the data according to specifications via the T-SQL? Also note that I would prefer to keep lookupCodeInfo() and especially am interested in keeping it enabled to accept lambda functions for specifying which rows/columns to return.

  • Sockets and multithreading

    - by V0idExp
    Hi to all! I have an interesting (to me) problem... There are two threads, one for capturing data from std input and sending it through socket to server, and another one which receives data from blocking socket. So, when there's no reply from server, recv() call waits indefenitely, right? But instead of blocking only its calling thread, it blocks the overall process! Why this thing occurs?

  • Making "helper" text in a form be a different color then typed text.

    - by aslum
    <input name="phone" type="text" id="phone" value="Phone #" onfocus="value=''"> I've got two problems here. The main one is I would like the helper text (in this case "Phone Number") to be a different color then the inputted text from the user, to make it easier for the user to differentiate between filled and unfilled fields. The second is that with this methodology (onfocus="value''") if you mistype something in a field and come back to it you have to retype the whole thing which isn't really acceptable.

  • Are duplicate directives in php.ini going to cause an issue?

    - by Brandon G
    I sent a request to ops today to update some php.ini directives, and found out that he merely appended them to the end of the file. My google search didn't really come up with any info on whether this is a problem or not to have duplicates in there and how they would be parsed. Obviously, it can cause confusion, but, I would have a stronger argument if I knew if this was acceptable or not. Any input? Thanks in advance...

  • Microsoft SQL Server 2005 Function, passing list of start and end times

    - by Kevin
    I'd like to do had a dynamic number of one start/end time pairs passed to a function as an input parameter. The function would then use the list instead of just one start, and one end time in a select statement. CREATE FUNCTION [dbo].[GetData] ( @StartTime datetime, @EndTime datetime ) RETURNS int AS BEGIN SELECT @EndTime = CASE WHEN @EndTime > CURRENT_TIMESTAMP THEN CURRENT_TIMESTAMP ELSE @EndTime END DECLARE @TempStates TABLE (StartTime datetime NOT NULL , EndTime datetime NOT NULL , StateIdentity int NOT NULL ) INSERT INTO @TempStates SELECT StartTime , EndTime , StateIdentity FROM State WHERE StartTime <= @EndTime AND EndTime >= @StartTime RETURN 0 END

  • How do I use a string as a keyword argument?

    - by Issac Kelly
    Specifically, I'm trying to use a string to arbitrairly filter the ORM. I've tried exec and eval solutions, but I'm running into walls. The code below doesn't work, but it's the best way I know how to explain where I'm trying to go from gblocks.models import Image f = 'image__endswith="jpg"' # Would be scripted in another area, but passed as text <user input> d = Image.objects.filter(f) #for the non-django pythonistas: d = Image.objects.filter(image__endswith="jpg") # would be the non-dynamic equivalent.
