php - Delete Rows from MySQL Database Using Checkboxes -

-

I am trying to delete a row from a table that is generated from a MySQL table. I took a look at these two questions: And I think both answers, but I am running into a problem. In each question, your checkbox is set in this way: 

  & lt; Input name = "checkbox [  
 and  
  & lt; Input name = "checkbox []" type = "checkbox" value = "& lt ;? php echo $ row ['topic_id'] ;? & gt;" & gt;   
 I am unable to use any of these in my code, because my table is generated in PHP, and using parentheses and quotations within my code (checkbox name Or value property, exact) throws a syntax error in magnificent, I am thinking that there is no alternative solution for this?  
 Here's a part of my table:  
  & lt; Tbody & gt; & Lt ;? Php $ query = mysqli_query ($ db, "SELECT * SOISInventoryList WHERE numInStock = 0 item by itemName"); If (! $ Query) {echo "query could not be taken."; } And {while ($ line = mysqli_fetch_assoc ($ query)) {echo "; tr & gt;"; Echo "& lt; td class = 'strikeOut' & gt; . $ Line ['item name'] "& lt; / td & gt;"; Echo "& lt; td class = 'strikeOut' & gt; . $ Line ['numInStock'] "& lt; / td & gt;"; Echo "& lt; td class = 'strikeOut' & gt; . "$" $ Line ['valuePriceUnit'] "& lt; / td & gt;"; Echo "& lt; td class = 'delete' & gt; . "& Lt; input type = 'checkbox' name = 'delete' & gt;"; Echo "& lt; / tr & gt;"; }}? & Gt; & Lt; / Tbody & gt;   
 Any kind of help or suggestions is appreciated. Your syntax problems (in a nutshell) come from the fact that you get the HTML of each line individually. Using echo command to print from For the type of work you are trying to do,  
  & lt ;? Php while ($ row = mysqli_fetch_assoc ($ query)):? & Gt; & Lt; TR & gt; & Lt; Td square = 'strikeout' & gt; & Lt ;? = $ Row ['itemName']? & Gt; & Lt; / TD & gt; (Other TD) & lt; Td class = 'delete' & gt; & Lt; Input type = 'checkbox' name = 'delete [& lt ;? = $ Row ['id']? & Gt;] '& gt; & Lt; / Td> & Lt; / TR & gt; & Lt ;? Php timeline? & Gt;   
 Printing in this way saves a lot of headaches (and feels great)!

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ...
