HTML - Unchecked Checkbox Not Posted
Yes, I know that an unchecked checkbox not posting is part of the html specifications. I'm just curious if anyone knows why this was desired behavior? If I have a form and I'm processing user input, input textboxes that are left blank yield an empty string. This makes processing them very easy. If I have checkboxes in my form, I have to test for a null value when referencing the checkbox by name prior to assigning or using its value. It would be far preferrable to simply have it submitted with checked="unchecked" (or false, whatever) so that it can be used immediately.
Similar TutorialsHi, I've recently started a website for a game i belong to and i have things like news items and feedback items, but i want my viewers to be able to post their comments on them and maybe leave a rating out of 5 stars or something like that for each item. I have only just recently started learning coding and this is my first site, so i'm not very experienced yet. But i have used a few php bits to create feedback forms, would it need that sort of thing? Or could it be done simply in html or javascript? If anyone knows of any online tutorials which cover this sort of thing i would appreciate it! Hello i want to get values passed from a webpage lets say siteA.html from another page siteB.html without php jsp or any server side language just html and javascript. If you can give an example on how to do this or an overview please do it. Thanks. I use blogger for my blog. Unfortunately, it does not give me the option to post the time AND date on every post, only one or the other. I chose to post the date, but I also want to know if anyone knows of an HTML code that can show the date the post was posted. If needed, my blog is http://www.freebie-link.com/. Any idea why the "theuploadedfile" input is not displayed when the program comes in after the submit ? PHP Code: <?php print 'Post=<pre>'; print_r($_POST);print '</pre>'; // PROBLEM $_POST['theuploadedfile'] IS NOT DISPLAYED (the text one is) ?> <form enctype="multipart/form-data" action="<?php print $_SERVER['PHP_SELF']; ?>" method="post"> <br>File to upload <input name="status" type="hidden" value="submitted"> <br>A<input name="thetexttype" type="text" size="100"> <br>B<input name="theuploadedfile" type="file" size="100" > <br><input name="submit" type="submit"> </form> Greetings all, i have a site that i've tested on my servers, and everything looks great in IE, FF, Eudora, etc... but then when i post it to the client's server, it appears fine in IE, but in FF (through Netscape), it gets these funny characters everywhere (see attached). Like 'A's w/ carats over them at the spaces and such... i don't know if this is something correctable in my code, or if it's a difference in hosting environments.

FYI: i did not write these codes How do you creat an unchecked checkbox in ZLS? Hi all! I wanna know how to personalise a checkbox... replacing the check off/on with an image (off and on). Can't find the script anywhere There's one for the radio button, but not for the checkbox Thanx Ray Hi: I would like to have a checkbox select input where I have approx 24 items for the user to select from. However, I want the user to *priority-order* his selections and have him/her select only a max of 8 of the 24 items. Instead of a 'checkmark, I would like to see the digits '1' up to '8' in the check boxes, which would indicate his priority order of choices. If this is impossible, can you suggest an alternative. (I don't want a drop-down list, I would prefer a 6-row, 4-column table of checkbox inputs). btw, this will be used by service providers to tell us which services they can/will provide to our Senior's Park, and in what priority they rate their various capabilities (from tree-pruning thru painting, thru yard cleanup, thru plumbling, re-modelling, etc). Thanks, -Mel Smith Hi there, Can anyone tell me the easiest way to make a form that only allows up to three checkboxes to be ticked? I've got a form with a question that asks 'which three of the following do you agree most with.' and there's about 10 checkboxes. How easy is it to limit the number to three? Many thanks! So, just have to say upfront that I don't really know HTML at all but my boss likes to throw me into things and lets me sink or swim. Basically, I need to update a database viewer that he wrote. The first (of sure to be many) problems are check boxes. Currently, when the user chooses a database and table from a drop down box then it shows the table with all the rows and columns showing. Note that the columns change based on the table selected. Now, I need the page to display a list of all the columns in that table as check boxes and when one clicks on a check box, it filters the table to show only the checked columns. I currently have the correct check boxes showing up based on the table but I am having trouble retrieving which columns have been checked for use in the actual filtering. Here's my current version of relevant code: HTML Code: <form name ="columnList"> Column: <c:forEach var="columnitem" items="${columns}"> <c:if test="${columnitem.name != this.document.columnList.name}"> <input type="checkbox" name="${columnitem.name}" id="${columnitem.name}" value="${columnitem.name}">${columnitem.name} </input> </c:if> </c:forEach> <th> <a href="onclick=javascript:setColumnsSelected('<c:out value='${columnitem.name}'/>')" </a> </th> </form> Code: function setColumnsSelected(column){ var colList = new Array(); if(this.document.getElementById(column).checked == true) colList.add(column); else colList.remove(column); } colList isn't used yet, but it will be. Can anyone help me out? Be gentle, I really have no clue what I'm doing. I have a page that has a checkbox. The checkbox is initially checked/unchecked depending on a value in a table. (Of course, the user has the ability to change this value once the page loads, this is just used for the initial value). The following code works, but does not validate using XHTML 1.0 STRICT: Code: <input type = 'checkbox' Name="chkComplete <?PHP print $chkComplete; ?> >Would you like to mark the item as completed? I know to validate to XHTML strict, I would need to code as either checked="checked" or unchecked="unchecked". How can I incorporate this into the PHP print or echo command so that the line will validate? Thanks. I have a simple HTML page that I would like to have 2 checkboxes available for the user to click. Now where this gets a little different: I do not want to have this "form" to function as a normal form, as this webpage is generated and displayed from within a desktop application (as a template). I essentially just want the user to click a checkbox and then click the print button from within the desktop application and have the webpage print with the checkbox checked. I am running into a problem because the checkbox that the user checked clears out when the user clicks the print button. I am assuming this is because I do not have any sort of "submit" method being used for this form (as it is just essentially a display for the user to check off an option that should then be printed as displayed on the screen). Is this at all possible? I am restricted to using HTML, CSS and XSL to build these web templates that are displayed in the desktop application so asp, javascript etc is not an option. Thanks for any help. Hi Guys, I've got 90 checkboxes in a table in a form on my index.html page. i.e: Code: <input type="checkbox" name="2e" id="2e"/> I would like one checkbox to be initially checked depending on the url used to get there e.g. Code: http://mysite.com/book/index?2e or http://mysite.com/book/index?2e=yes Any Ideas? Thanks, Leigh Hello, I am having troubles getting the below to work. Can someone help me out? Thanks in advanced. How do i get the below to work? Java if (document.orderform.terms.value== false) { alert("You must agree to our terms and conditions before an order can be processed") document.orderform.terms.focus() return false } HTML: <p>By clicking on the below you have read and agree to our terms and conditions</p> <input type="checkbox" name="terms" /><p>I Agree</p> i'm an idiot novice and i have a set of checkboxes i want to display... <table> <tr> <td> <input name="1" type="checkbox" value="1" />PROVISIONAL<br/> <input name="2" type="checkbox" value="2" />COMPLETE<br/> <input name="3" type="checkbox" value="3" />PARTIAL<br/> <input name="4" type="checkbox" value="4" />FINAL<br/> <input name="5" type="checkbox" value="5" />PROGRESS<br/> <input name="6" type="checkbox" value="6" />ADVANCE </td> </tr> </table> however, when it displays on the page...they are staggered like this... one two three etc. i can add another break after each checkbox but that puts too much space between each checkbox....is there anything i can do? thanks in advance! In my imaginary web page, I have a list of products. I also have a list of questions with (Yes) and (No) checkboxes beside them. If (No) is checked for question 1, the text for product 2 and 3 must change to grey instead of black. Etc. How could I do this? Hi Guys, The form below is part of a new ticketing system i am playing around with. I dont know much about it yet but i want to add a mandatory checkbox to the form and also a text area which contains my terms and conditions. The form below is part of submitting a new ticket and before they can do so i want them to have to check the box below my terms and conditions saying they have read and agree. I'm no expert on forms but im guessing this could be acheived by adding a text area and a checkbox. Most important thing >>>> If the checkbox is not checked i want a pop up warning to pop up saying please tick the box or something like that. Heres the form anyway: Code: <form name="new_ticket" method="post" action="new_ticket.php" onSubmit="return validate_ticket(document.new_ticket);" enctype="multipart/form-data" > <input type="hidden" name="act" value="openticket"> <div class="sub-heading"> {{cClient_newtickettitle}} </div> <div class="formheading"> <span class="label"> {{cLogin_direct}} </span> </div> <div class="formrow"> <span class="label">{{cClient_fullname}}:</span> <span class="field"><input name="client_name" type="text" class="singleline-field" id="full_name" value="{{client_name}}" /> <span class="mandatory-fld"> * </span> </span> </div> <div class="formrow"> <span class=label> {{cClient_phone}} : </span> <span class="field"> <input type="text" name="phone" value="{{phone}}" class="singleline-field"> </span> </div> <div class="formrow"> <span class="label"> {{cClient_email}} : </span> <span class="field"> <input type="text" name="email" value="{{email}}" class="singleline-field"> <span class="mandatory-fld"> * </span> </span> </div> <{customfields_loopstart}> <div class="formrow"> <span class="label"> <{field_name}> : </span> <span class="field"> <{draw_field}> </span> </div> <{customfields_loopend}> <div class="formrow"> <span class=label> {{cDepartment}} : </span> <span class="field"> <select name="dept_id" class="singleline-field"> <option value="">{{cSelect}}</option> <{dept_loopstart}> <option value="<{dept_id}>" <{selected}> ><{dept_name}></option> <{dept_loopend}> </select> <span class="mandatory-fld"> * </span> </span> </div> <div class="formrow"> <span class=label> {{cTicket_priority}} : </span> <span class="field"> <select name="priority_id" class="singleline-field"> <option value="">{{cSelect}}</option> <{priority_loopstart}> <option value="<{priority_id}>" <{selected}> ><{priority_name}></option> <{priority_loopend}> </select> <span class="mandatory-fld"> * </span> </span> </div> <div class="formrow"> <span class=label> {{cTicket_subject}} : </span> <span class="field"> <input type="text" name="subject" value="{{subject}}" class="textarea-field"> <span class="mandatory-fld"> * </span> </span> </div> <div class="formrow"> <span class=label> {{cTicket_message}} : </span> <span class="field"> <textarea name="message" cols="{{cols}}" rows="{{rows}}" class="textarea-field" id="comments">{{message}}</textarea> <span class="mandatory-fld"> * </span> </span> </div> <{attachment_start}> <div class="formrow"> <span class=label> {{cTicket_attachment}} : </span> <span class="field"> <input type="file" name="attachment" value="" size="50" /> ({{cMax}} {{attachment_size}} {{cKb}}) </span> </div> <{attachment_end}> <div class="formheading"> <span class="label"> {{cProvide_password}} </span> </div> <div class="formrow"> <span class="label"> {{cPassword}} : </span> <span class="field"> <input type="password" name="pass_word" class="singleline-field"> <span class="mandatory-fld"> * </span> </span> </div> <div class="formrow"> <span class="label"> {{cPassword_confirm}} : </span> <span class="field"> <input type="password" name="password_confirm" class="singleline-field"> <span class="mandatory-fld"> * </span> </span> </div> <div class="formrow"> <span class="field"> <input type="submit" name="Submit" value="{{cSubmit}}" class="stdbutton-field" /> <input type="reset" name="reset" value="{{cReset}}" class="stdbutton-field" /> </span> </div> </form> I also have a number of other forms i will want to add this feature too so if anyone edits the code please highlight the part you added for me to see easily and then i can just copy it to my otehr forms.
