How can I fetch selected data to an object and retrieve the selected columns name with PDO?
Now, I'm fetching to a Member object in a loop, and manually add each column to the object by accessing it from the "fetch array". Is there a way to automatically get the column names that's been seleced?
$sql = "SELECT member.name, member.email FROM member WHERE id = :id";
$param = array(':id' => $id);
$stmt = $this->m_db->select($sql, $param);
$ret = new MemberArray();
while ($f = $stmt->fetch()) {
$member = new Member($f['name'], $f['email']);
$ret->add($member);
}
return $ret;
I found the solution in PDOStatement::bindColumn and PDO::FETCH_OBJ

I am trying to copy data from one list to other list (both lists are on different sites) along with lookup columns. But, I am getting an error for lookup field as:
Value does not fall within the expected range
Code works and data gets copied for other non-lookup fields. I tried every possible way including increasing List View Lookup Threshold and all possible ways of code but still error persists at ExecuteQuery().
Below is my code for lookup field:
if (field is FieldLookup && field.InternalName == "Country")
{
var CountryLookup = (item.FieldValues["Country"] as FieldLookupValue).LookupValue.ToString();
var CountryLookupId = (item.FieldValues["Country"] as FieldLookupValue).LookupId.ToString();
FieldLookupValue flvRDS = new FieldLookupValue();
flvRDS.LookupId = int.Parse(CountryLookupId);
itemToCreate["Country"] = flvRDS;
itemToCreate.Update();
destContext.ExecuteQuery();
}
Help is really appreciated.
I assume item is the new ListItem you're trying to create on your target list.
But you're never in fact reading any value from field here! So basically, you're trying to set your new FieldLookup.LookupId with the item["Country"].LookupId, which should logically be empty at this moment.
Here's a method I use to retrieve a lookup field ListItem from a value, feel free to modify it to fit your need, since I don't know how you want to retrieve it (SPList is an alias for Microsoft.SharePoint.Client.List).
private ListItem GetLookupItem(FieldLookup lookupField, string lookupValue)
{
string mappingField = lookupField.LookupField;
Microsoft.SharePoint.Client.List lookupList = Context.Web.Lists.GetById(new Guid(lookupField.LookupList));
Context.Load(lookupList);
Context.ExecuteQuery();
ListItemCollection libListItems = lookupList.GetItems(CamlQuery.CreateAllItemsQuery());
Context.Load(libListItems, items => items.Include(
itemlookup => itemlookup.Id,
itemlookup => itemlookup[mappingField]));
Context.ExecuteQuery();
foreach (ListItem mappedItem in libListItems)
{
object mappedField = mappedItem[mappingField];
if (mappedField != null && mappedField.ToString().Equals(lookupValue))
return mappedItem;
}
return null;
}
Now that you have the corresponding ListItem, you can set your item.LookupId with its Id:
if (field is FieldLookup && field.InternalName == "Country")
{
FieldLookupValue flvRDS = new FieldLookupValue();
flvRDS.LookupId = GetLookupItem(field as FieldLookup, "France").Id; // here, dunno how you get your country's name
itemToCreate["Country"] = flvRDS;
itemToCreate.Update();
destContext.ExecuteQuery();
}
Feel free to add some more previous code if you want an answer more suited for your specific issue.
Having a problem with the code below only adds the latest value in the TestTaxonomyControl.Text to the metadata column. ( multiple values is turned on )
TaxonomyFieldValueCollection values = new TaxonomyFieldValueCollection(String.Empty);
values.PopulateFromLabelGuidPairs(TestTaxonomyControl.Text);
TaxonomyField entKeyword = (TaxonomyField)item.Fields["Metadata"];
foreach (TaxonomyFieldValue value in values)
{
TaxonomyFieldValue term = new TaxonomyFieldValue("1;#" + value.Label + "|" + value.TermGuid);
entKeyword.SetFieldValue(item, term);
}
item.Update();
I'd say you only need something like:
TaxonomyFieldValueCollection values = new TaxonomyFieldValueCollection(String.Empty);
values.PopulateFromLabelGuidPairs(TestTaxonomyControl.Text);
item["Metadata"] = values;
item.Update();
How can I insert an object in database in kohana 3?
My code is:
$application = DB::query(Database::SELECT,"SELECT * FROM application_settings WHERE 'id' = 1")->as_object()->execute();
$application -> google_analytical = $_POST['google_txt'];
$application = DB::insert('application_settings',$application)->execute();
$this->template->inner->status_msg = "Record has been saved successfully";
I want to insert the object named application into the database.
DB::insert() syntax is:
DB::insert('application_settings', $application_columns)
->values($application_values)
->execute();
By the way, why do you want to INSERT new record instead of UPDATEing an existing one?
DB::update('application_settings')
->set(array('google_analytical' => $_POST['google_txt']))
->where('id', '=', $application->id))
->execute();
UPD. You are looking for a single row, so:
// insert it after DB::query() call
$application = current($application);
I have a lookup field in sharepoint which just references another list. I wonder how do I programatically enumerate all possible values for this field?
For example, my lookup field "Actual City" refers list "Cities" and column "Title", I have 3 cities there. In code I would like to get list of all possible values for field "Actual City", smth like (metacode, sorry):
SPFieldLookup f = myList["Actual City"];
Collection availableValues = f.GetAllPossibleValues();
//this should return collection with all cities a user might select for the field
I wrote some code to handle this for my project just the other day. Perhaps it will help.
public static List<SPFieldLookupValue> GetLookupFieldValues(SPList list, string fieldName)
{
var results = new List<SPFieldLookupValue>();
var field = list.Fields.GetField(fieldName);
if (field.Type != SPFieldType.Lookup) throw new SPException(String.Format("The field {0} is not a lookup field.", fieldName));
var lookupField = field as SPFieldLookup;
var lookupList = list.ParentWeb.Lists[Guid.Parse(lookupField.LookupList)];
var query = new SPQuery();
query.Query = String.Format("<OrderBy><FieldRef Name='{0}'/></OrderBy>", lookupField.LookupField);
foreach (SPListItem item in lookupList.GetItems(query))
{
results.Add(new SPFieldLookupValue(item.ID, item[lookupField.LookupField].ToString()));
}
return results;
}
Then to use it, your code would look something like this:
var list = SPContext.Current.Web.Lists["My List"];
var results = GetLookupFieldValues(list, "Actual City");
foreach (SPFieldLookupValue result in results)
{
var value = result.LookupValue;
var id = result.LookupId;
}
I think there is no explicit method returning what you want. But the SPFieldLookup class stores all the info you need to request this information manually: LookupField and LookupList
So you could retrieve the information by getting it form the list you lookup field uses. To make it reusable you could implement it as a Extension Method. So the next time you could really call f.GetAllPossibleValues();.
As I understand you want to query all values that are in use?
If so, you would have to query items where Actual City is not null, query would look something like:
<Where><IsNotNull><FieldRef Name='Actual City'/></IsNotNull></Where>
Then, for each queried item you would
List<SPFieldLookupValue> result = new List<SPFieldLookupValue>(returnedItemCount * 5);
foreach (SPListItem item in queriedItems) {
object lookup = item["Actual City"];
SPFieldLookupValueCollection lookupValues = new SPFIeldLookupValueCollection(
(lookup != null) ? lookup.ToString() : ""
);
foreach (SPFieldLookupValue lookupValue in lookupValues) {
if (!result.Contains(lookupValue)) {
result.Add(lookupValue);
}
}
}
Or you could use HashTable where LookupId would be string and LookupValue would be int id and then check if HashTable.ContainsKey(lookupId)... must be faster to find an integer in hashtable rather than string in list, but the resource intensive part is to probably query all items where that field contains some value and then loop...
If you want to enumerate all possible values, that means you basically want to get all the Title field values from all the items in the Cities list. I don't think there is a method like GetAllPossibleValues() in SharePoint, but you can either just list all the items in Cities and get their titles, if there's just a few, or use a CAML query if there's plenty.
$sql = sprintf( "SELECT topic_title
FROM `phpbb_topics`
WHERE `topic_title` LIKE '%%%s%%' LIMIT 20"
, mysql_real_escape_string('match this title')
);
Which I run this query in phpMyAdmin the results are: (correct)
match this title
match this title 002
But when I run that same MYSQL query in PHP I get: (incorrect)
match this title 002
I have also tried MATCH AGAINST with the same result with both php and phpMyAdmin:
$sql = "SELECT topic_title
FROM phpbb_topics
WHERE MATCH (topic_title)
AGAINST('match this title' IN BOOLEAN MODE)";
The whole block of code im using to search with:
mysql_connect("localhost", "user", "pass") or die(mysql_error());
mysql_select_db("phpbb") or die(mysql_error());
$query = "match this title";
$query = "SELECT topic_title
FROM phpbb_topics
WHERE MATCH (topic_title)
AGAINST('$query' IN BOOLEAN MODE)";
// Doesn't work (these 2 both give the same result "match this title 002" and no the "match this title")
// $query = "SELECT * FROM `phpbb_topics`
// WHERE `topic_title`
// LIKE '%$query%'
// LIMIT 0, 30 "; // Doesn't work
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($result) or die(mysql_error());
while($row = mysql_fetch_array($result)){
$topic_title = $row['topic_title'];
echo "$topic_title";
}
Any idea as to what i'm doing wrong?
I'v been searching all over the place and have found next to no help :(
The problem is that after you execute your query you fetch the first row, do nothing with it, enter the loop by fetching the second row and start printing results..
If you remove the first $row = mysql_fetch_array($result), (directly after $result = mysql_query($query) or die(mysql_error());) you should be fine.
Another comment; If you echo a variable you don't have to put any qoutes around it. And in the way you're doing it now, you won't get a newline between the results so you might want to change that line to echo $topic_title . "<br>";
