mysql - php submit with PDO SQL issue -

-

I wanted to change the PDO from the normal mysql query but since then I can not track the error back too.

Is there anyone to help me out there? Any sign will be appreciated!

Question 1: What's wrong? Question 2: How can the mistake be tracked in general? 

  & lt ;? Php // If you activate the activate button, start it (isset ($ _ POST ['create'])) {$ new = htmlspecialchars ($ _ post ['newgroup']); $ Sql ​​= "Include in contact groups (status, gr_name) value (1,: new)"; $ Sql- & gt; Bindview (': new', $ new); $ Sql- & gt; Executed (); $ Arr = $ sql-> errorInfo (); Counter $ arr; Echo "& lt; meta http-equiv = \" refresh \ "content = \" 0; URL = groups.php \ "& gt;"; }? & Gt; & Lt; Form id = "group-in" method = "post" action = "groups.php" & gt; Add new distribution group: & lt; Input type = "text" name = "newgroup" placeholder = "name ..." & gt; & Lt; Input type = "submit" name = "create" value = "create new" & gt; Rename group name: & lt; Input type = "text" value = "& lt ;? php echo $ result ['gr_name'] ;; & gt; & Gt; & Lt; Input type = "submit" name = "rename" value = "rename" & gt; & Lt; / Form & gt; $ _POST is coming up, SQL is running but nothing after bindPARAM / bindVALUE ...   
 
 
 You never make up your own SQL statement.  
 To run, you must first initialize DB and create a new PDO example. Assume that you have done this before:  
  & lt ;? Start Php // if activate the activate button, start it (isset ($ _ POST ['create'])) {$ new = htmlspecialchars ($ _POST ['newgroup']); $ Sql ​​= "Include in contact groups (status, gr_name) value (1,: new)"; $ Stmt = $ db- & gt; Ready ($ sql); $ Stmt- & gt; Bindview (': new', $ new); $ Stmt- & gt; Executed (); $ Arr = $ stmt-> ErrorInfo (); Counter $ arr; Echo "& lt; meta http-equiv = \" refresh \ "content = \" 0; URL = groups.php \ "& gt;"; }? & Gt;   
 You can wrap the Function / Code Bit with an attempt / catch statement and enable exception handling with PDO so that better information is found in the errors going forward.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
